Effectiveness of heat exchangers with one shell pass and three tube passes. Master's thesis

Technical Report ·
OSTI ID:6124237

Heat exchangers with one shell pass and n tube passes are often referred to as 1-n exchangers. The heat-transfer literature contains many references to studies of 1-n exchangers when n is even but apparently little work has been done with respect to the 1-n exchanger when n is odd. This thesis greatly expands the theoretical study of 1-n exchangers with n being odd. While a completely closed-form solution was found to be unfeasible, a polynomial approximation was developed that yields the effectiveness of the two possible arrangements of the 1-3 exchanger as a function of the capacity-rate ratio and the number of transfer units. It is also shown that the effectiveness of the arrangement with two counterflow and one parallel flow tube side passes exceeds that of some of the 1-n exchangers with n even.
