SimScape- question on thermal capabilities

[Vitaliy Churilov]

Good day All,

I am looking to model a heat loss in a pipe with SimScape, but I am not sure if this is the right application for the job. Also it is very difficult to understand what governing equation used in the application without having it.

I know that the equation for one dimensional steady state conduction are different for rectangular or cylindrical bodies, but I am looking for one dimensional transient heat transfer in a pipe.
My questions are: Can SimScape simulate transient heat transfer application of conduction and convection (in 1D pipe) out of the box?
If not, Is it possible to build this in SimScape?
If yes, has any one done it and willing to share this application?

Thank you for your help

Here is the response from Simscape development team:

1. Can SimScape simulate transient heat transfer application of conduction

and convection (in 1D pipe) out of the box?

You can simulate transient heat transfer through conduction,
convection, or emission in Simscape. The only limitation Simscape imposes on
the model is the requirement to describe the process in lumped parameters.
If this is applicable to your system, you can use thermal blocks from the
foundation library and build a model of your system. The documentation
contains all the equations necessary for understanding Simscape's approach
to thermal system simulation.
Things are different if you are dealing with the heat and mass
transfer problems in hydraulic or gaseous systems. Simscape does not have
ready to be used blocks at this moment for this type of applications.

2. If not, Is it possible to build this in SimScape?
It is possible.

3. If yes, has any one done it and willing to share this application?
There are three demos in Simscape demonstrating usage of thermal
blocks: House Heating System, DC Motor Thermal Circuit, Heat Conduction
through Iron Rod.

Hope this helps solving your problems.

In addition to Jacek's detailed answer, the complete Simscape documentation is available on the MathWorks web site. For examples, the documentation for the conduction, convection and radiation blocks is available at:
