Heat Transfer Software Free

Please accept our thanks and congratulations for your very interesting work which I am sure are having a great positive impact in our society.” — from Roberto Quevedo, Instituto Volcanológico de Canarias, INVOLCAN, Puerto de la Cruz, Tenerife, Canary Islands, Spain.

Based on computational physics, Energy2D is an interactive multiphysics simulation program that models all three modes of heat transfer—conduction, convection, and radiation, and their coupling with particle dynamics.

Energy2D runs quickly on most computers and eliminates the switches among preprocessors, solvers, and postprocessors typically needed to perform computational fluid dynamics simulations.

It allows you to design "computational experiments" to test a scientific hypothesis or solve an engineering problem without resorting to complex mathematics.

Modes of Heat Transfer

Work is also underway to incorporate other types of energy transformations (e.g., phase changes and chemical reactions through the Stefan condition) and support multiple types of fluids (e.g., air and water).

Charles Xie, Interactive Heat Transfer Simulations for Everyone, The Physics Teacher, Volume 50, Issue 4, pp. The conduction part of Energy2D is highly accurate, but the convection and radiation parts are not 100% accurate.

Hence, in cases that involve convection and radiation, Energy2D results should be considered as qualitative.

What is it?

The pictures to the right show a comparison of the results of Energy2D simulations with images from infrared thermography for a simple model house.

The thermal patterns predicted by Energy2D roughly match those from a thermal camera. More than 40 scientific papers have used Energy2D as a research tool (not just a citation), demonstrating its wide applications across science and engineering.

The following is a list of books that have recommended Energy2D: .

“..we have suggested the adoption of the platform Energy2D for a very effective “what-if” game in terms of the construction of cases of study eventually much more complex than the one here addressed.

How well does it model reality?

We have shown a solid reliability of the simulation in the description of our experiment: it can open the way to a basically unlimited number of applications, including those, for example, in which convective transport phenomena play a non-negligible role.” — from Stefano Oss, European Journal of Physics.

“The software program Energy2D is used to solve the dynamic Fourier heat transfer equations for the Convective Concrete case. Energy2D is a relatively new program (Xie, 2012) and is not yet widely used as a building performance simulation tool.

To gain more confidence in the predictions with Energy2D, an analytical validation study was therefore carried out first, inspired by the approach described in Hensen and Nakhi (1994).

How to cite it?

Those analytical solutions and the simulation results of the dynamic response to a 20°C temperature step change on the surface of a concrete construction with the following properties were compared for this research..

the simulation results never divert from the exact solution more than 0.45°C and it is therefore considered acceptable to further use this model.” — Dennis de Witte, Marie L.

“Thank you for your absolutely great app which helps me a lot for visualizing my lecture in thermodynamics.

How many papers have used it?

It is also very nice to see that three platforms are supported and every single one is free to use.

That is just awesome and I want to say thank you for all users.

I do not know how many messages of this type you are receiving.” — from Martin Weise, Austria. “In gearing up to teach a course called Building Science this semester, I somehow stumbled across your program Energy2D and Energy3D.

I was really impressed by how simple and easy these tools were and I'm definitely going to integrate them into some portion of my lectures.”— Prof.

How many books have recommended it?

“I am currently involved in renewable energy related research activities and teaching. I have downloaded and demonstrating Energy2D for my heat transfer course. It is really a very useful tool.”— Dr.

Mazharul Islam, Department of Mechanical Engineering, Taibah University, Saudi Arabia. “Today during the lunch break a little simulated comparison fan in the suction and blowing operation collector here about 50x70 cm and fan with 2 meters / second.

[The result] is confirmed by the experiences of several users: pressure losses and less volume of air in the blowing operation.” (Link to the source).
