Introduction of   PDPD-Magic @@heat exchanger analysis sytem of on demand tankless water heaters

 

Before thermal stress analisys  calculation of fulud dynamics by Pf-Magic  is indispensable

PF-magic is fulid dynamics anslysis software for design heat exchanger of tankless water heaters. 

User can do quite easy parameter fluid dynamics study by PF-Magic. .

 

  

Meshing (Completely Automatic) fin by Pf-Magic Data

Transpoprt to PD-magic from PF-magic is quite easy .

User can easily know how fin design and fluid dynamics affect to thermal stress

 

 

 

 

 

 Examples of Result of Finite element method at heatexchanger

 

Following Picures are Full Finite Element Model of Heat Exchanger Generated from Pf-Magic data

 

 

Example of Crack Risk at the wall caused by thermal expansion.(Thermal Stress)

 

 

Get knowing how fluid dynamics effects to Fin and Pipe and walls Etc.

thermal expansion at fin match depends on fin temperature

and Fin temperature is match affected by fluid dynamics.

 

Example od Mises STRESS at wall.
