Programs for thermodynamics calculations

In summary, the conversation discusses the use of programs to perform thermodynamic calculations, specifically in a piston-cylinder arrangement. The question is whether multiphysics programs have an advantage in performing these calculations compared to other programs such as numerical analysis programs or CAS. The conversation also mentions the possibility of using ProPhyPlus, a Java script based program, and references a paper discussing the use of spreadsheets for thermodynamic calculations. The mention of British Gas and the suggestion to follow up on it may be related to the use of a program to perform these calculations. Overall, the conversation highlights the various options available for performing thermodynamic calculations and raises the question of whether multiphysics programs have an advantage in this task.

I know these calculations in thermodynamics can be done by hand or a simple calculator but I wonder if some programs do these calculations. These programs might be called multiphysics programs. An example of a calculation - select piston-cylinder arrangement.
-enter initial volume and pressure; P1 V1
- enter final volume and polytropic exponent
- calculate work done
This calculation can be performed in numerical analysis programs or CAS but can multiphysics programs have an advantage?

Thank you.

British Gas did precisely this and I know the programmer if you are interested?

have you tried ProPhyPlus? its fairly easy to use.

Otherwise there are lots of Java script based programmes to calculate Gibbs Free

but this is worth following up: http://www.csun.edu/~lcaretto/paper/spreadsheet calculations of thermodynamic properties.pdf

This is the first time for British Gas, ProPhyPlus and Gibbs Free for me.

Thank you.

What do you mean by I know the programmer? Do you mean program itself?

Meanwhile can some multiphysics programs do such things? Is "British Gas" a multiphysics program. When I googled it I saw a company not a program.

Thank you.
 

FAQ: Programs for thermodynamics calculations

What is thermodynamics and why is it important?

Thermodynamics is the study of energy and its transformations, particularly in relation to physical systems. It is an important field because it helps us understand how energy is used and transferred in various processes, from everyday activities to large-scale industrial processes.

What are the basic principles of thermodynamics?

The basic principles of thermodynamics include the laws of thermodynamics, which state that energy cannot be created or destroyed, only transferred or transformed, and that the total entropy of a closed system always increases. Other key principles include temperature, heat, and work.

What are some common applications of thermodynamics?

Thermodynamics has many practical applications, including in the fields of engineering, chemistry, and physics. Some common applications include power generation, refrigeration and air conditioning, chemical reactions, and materials processing.

What are some commonly used programs for thermodynamics calculations?

Some commonly used programs for thermodynamics calculations include MATLAB, Aspen Plus, and ChemCAD. These programs use mathematical models and algorithms to solve complex thermodynamic equations and perform calculations for various processes and systems.

What are the benefits of using programs for thermodynamics calculations?

Using programs for thermodynamics calculations allows for faster and more accurate results compared to manual calculations. It also allows for complex systems to be modeled and analyzed, helping scientists and engineers make informed decisions and optimize processes for energy efficiency.
