The Recuperative Heat Exchangers – The Mean Temperature Difference in the Special Cases of Heat Transfer

The Recuperative Heat Exchangers – The Mean Temperature Difference in the Special Cases of Heat Transfer

The heat exchangers are used to heat or cool the material streams. To calculate the heat exchanger, it is important to know the type of heat exchanger and its operating characteristic. This characteristic determines one of the key variables (e.g., F, NTUmin, or θ). In some special cases, it is not n...
