Hello,

I had a problem in Simscape / Simulink

I have custom matlab box that outputs temperature and mass flow rate signal as show in the figure. I converted them into physical signal further.

I would like to combine them into a single physical quantity such that it can be connected to A1 port in the Gas-Liquid heat exchanger. Is there a way we can combine the two signals into a gas(physical) ?

Thanks

Hi Asutosh,

I understand you want to use the ‘Heat Exchanger(G-TL)’ in Simscape and want to combine the ‘Temperature’ and the ‘Mass Flow Rate’ information into a single physical quantity to pass it as an input to the ‘Gas-Liquid Heat Exchanger’ Block.

I believe you don’t need to combine the ‘Temperature’ and ‘Mass Flow Rate’ into a single physical quantity to use them in the ‘Heat Exchanger(G-TL)’ block. You need to pass the ‘Mass Flow Rate’ information into the A1 inlet and the ‘Temperature’ into the B2 inlet.

You could refer the following documentation to learn more about ‘Heat Exchanger(G-TL)’ block: https://www.mathworks.com/help/hydro/ref/heatexchangergtl.html

You could refer the following example which uses the ‘Heat Exchanger(G-TL)’ and has ‘Temperature’ and ‘Air Flow Rate’ as individual components: https://www.mathworks.com/help/hydro/ug/ev-battery-cooling.html

The ‘Heat Exchanger(G-TL)’ block is present at ‘ EVBatteryCoolingSystem/Heating-Cooling Unit/Radiator’.

I hope this helps.
