Sample Heat Transfer Simulations
Periodically ThermoAnalytics will be presenting a new model for you to view. Check back here for new models.
July 2010: Aircraft Cabin Thermal Design
The focus of this sample model is to use thermal design to improve the aircraft’s human comfort while reducing the power load on its climate control system. Two cases were created: a baseline aircraft case and a second case with improved thermal design and reduced air flow from the climate control system.
April 2009: AC Pull down with Berkeley Human Comfort Model
This sample demonstrates an evaluation of AC pull-down using two different source air temperature profiles and the resulting effects on localized passenger comfort using the integrated Berkeley Comfort Model.
October 2008: Cathedral of Christ the Light
ThermoAnalytics was approached in 2005 to perform an architectural thermal comfort analysis of the structure. The Cathedral, completed in 2008, was in need of calculations to help predict solar loading as well as air circulation patterns throughout the structure.
August 2008: Thermal Image Mapping
This tutorial will demonstrate how to import a texture-mapped image into ThermoAnalytics software and applying the temperature distribution mesh to a part.
May 2008: Multiple Human Thermal Comfort
This sample model demonstrates the use of RadTherm and MuSES to predict transient thermal comfort for multiple humans in realistic environments, in this case, a hot desert environment. This type of analysis provides realistic, localized loading of the air nodes inside the vehicle from both the inert surfaces and the human metabolism.
February 2008: Face-to-face and Solids
These sample models demonstrate the groundbreaking new features in Version 9.0 and include print and video tutorials illustrating the very straightforward workflow. The heatsink model demonstrates conduction with solid objects using the Boundary Element Method, and includes simple objects representing a basic heat source, silicon wafer, and circuit board. The Pipe Hanger model represents a common thermal problem of ducts and pipes conveying hot liquids - thermal protection of the supporting hardware.
August 2007: Human Thermal Comfort Simulation for Architectural Analysis
The ThermoAnalytics Human Comfort Module is a collection of user routines and property database that is available under a separate license to operate with RadTherm, RadThermIR or MuSESPro to simulate the thermal response of a human body when exposed to environments with significant thermal loads.
March 2007: Silverstone Racetrack Thermal Analysis
This sample model demonstrates the use of RadTherm in predicting racetrack surface temperatures for use in Formula 1 racing. The use of simulation for strategic planning, based on forecasted weather and effects on track temperature, can be a powerful ally in an event where the winner is only seconds ahead of the competition.
August 2006: Oil-Water Heat Exchanger
In order to demonstrate the fluid stream and convection heat transfer modeling capabilities of RadTherm, a coil-in-tube cross flow heat exchanger was simulated. The heat exchanger has hot engine oil (126°C at the inlet) flowing in the inner coil at 1.5 liter/min and water (90°C at the inlet) flowing in the larger cylinder at 10 liter/min.
May 2006: DC-10 Airliner during Passenger Boarding through Jetway in Phoenix
This sample model highlights the transient analysis and environmental loading analysis capabilities of RadTherm. The sample DC-10 airplane is parked on the Phoenix International Airport runway during passenger boarding on a hot summer day in Arizona.
December 2005: Commercial Light Truck with Refrigerated Cargo Box
This sample model highlights the unique combination of RadTherm features that enable comprehensive thermal analysis of complex systems. In this case, the system is a commercial vehicle used for transportation of cargo under a controlled, refrigerated environment. The vehicle's thermal behavior and the cargo system thermal response are simulated.
September 2005: Motorcycle Transient Simulation
One of the most frequent customer complaints about motorcycles is the heat plume that rises from the engine and hits the rider while idling in traffic or after getting off the highway. Because many engines are air-cooled, its heat will rise from the cooling fins in a thermo-buoyant manner and strike the rider when there is no airflow around the engine. This analysis was performed to simulate the heat plume and predict the increase in temperatures the rider will experience.
July 2005: Office Building with Imported CFD Wind Convection
This sample model demonstrates RadTherm's unique environmental effects applied to architectural analysis. By combining CFD results with RadTherm's advanced thermal analysis, transient thermal results can be generated with minimal computation time.
February 2005: Vented Brake Rotor with Wheel and Tire
The geometry for the brake model is loosely based on the front rotors for a 2005 Ford Mustang. The exact dimensions were unknown so the majority of the dimensions are approximate. The geometry was modeled in Rhinoceros 3D and meshed using Eclectic.
June 2004: Heated Aluminum Plate with Scripted Thermostat Controls
This model demonstrates the use of scripts in RadTherm/MuSESPro Version 7.1 to simulate simple thermostatic control of two heating systems. The steps to develop and implement this model are shown below. This model represents a common heated plate system used in many manufacturing operations.
February 2004: Tents under Winter Forest Canopy
This Model of the Month highlights the modeling of natural environments and canopy clutter with our software. Modeling the forest canopy can be important for generating accurate temperatures or IR signatures of objects in such environments.
November 2003: Heat Shield: using TDFUtility to improve mesh quality
This Model of the Month focuses on a modeling development process using the supplemental TDFUtility program (supplied with all software from ThermoAnalytics), rather than on a specific application of thermal analysis.
October 2003: Hybrid Unmanned Ground Vehicle
This model includes a hybrid electric drive train with battery storage in the rear of the vehicle. Additional heat sources are the internal electronics, sensor tower, lights, and transient solar loads. The engine and exhaust inlet are active for models where the vehicle is idling or exercised.
July 2003: Combined RadTherm-CFD Automotive Underbody Analysis
This model of the month demonstrates the power of RadTherm's CFD import function. An iterative method of analysis that utilizes RadTherm with supporting CFD analysis was used to predict the underbody surface temperatures of a moving automobile.
April 2003: Diesel Truck
This model was created to demonstrate the built-in Diesel Engine Model in RadTherm/MuSES Version 7.0. The engine model can be "driven" using a vehicle speed input curve.
November 2002: Brake Rotor
This model was created to approximate the transient heating of a brake rotor on a vehicle with gross weight 2000 kg.
July 2002: Room Heater
June 2002: Jeep
Two models are presented in this Model of the Month—a steady state and a transient model. Both use the same Jeep Geometry developed from photos of a 97 Jeep Grand Cherokee (Trademarks of DaimlerChrysler). The model was developed with 37 total parts, including 9 fluid parts (coolant heat source to the radiator, advective air nodes underhood, etc.).
May 2002: Oven
This model was developed to illustrate the use of RadTherm and Wintherm for thermal process development. In this example, a large motor-pump system is passing through a paint-curing oven.
April 2002: House
This model used weather data from an early July day in the northern midwest United States (47N,88W). Over approximately 16 hours, the day started with a clear, cool morning sunrise, followed by varying cloudiness, which can be recognized in the animations as hot-cold variations of the exterior surfaces.
March 2002: Stonehenge
December 2001: Coffee Maker
November 2001: Heat Exchanger
In addition to high speed radiation and conduction analysis, RadTherm's convection library gives you powerful 1-D tools for advection analysis. Your models are set up quickly through the graphical user interface.
