Which method do you use for heat exchanger design?
The two most commonly used are the ュ-NTU and LMTD methods. In this section a PSR recuperator of the plate type is discussed using the ュ-NTU method.
What method is heat exchanger analysis?
Heat exchanger analysis is quite complicated and involves flow parameters and geometry quite heavily. Some simpler methods of analysis are the Log-Mean Temperature Difference (LMTD) method and the Number of Transfer Unit (NTU) method.
What is the kern method of heat exchanger design?
Kern's method Kern's method is a widely used approach for designing heat exchangers. It is based on the principle of heat transfer and fluid mechanics, and it takes into account the physical properties of the fluids involved, the geometry of the heat exchanger, and the operating conditions.
