Dear All,

 

Thank you for any comment and advice in advance.

 

When I checked out the HTRI input file by thermal design engineer, I could not understand how critical temperature and pressure be operated and generated the specific result according to those critical properties?

Especially, reboiler or condenser where phase change occurs, critical properties are meaningful.

 

Please let us know how these critical properties play a role in HTRI rating and heat exchanger design?

 

Best regards

While there is a lot of detail that I necessarily will not go into, most of our thermal property calculations these days are performed using various equations of state (peng robinson, for example). At the heart of many of these EOS is the principle of corresponding states (http://en.wikipedia....sponding_states ). So, critical properties are a key input to these equations.

@MrShorty I appreciate it
