Abstract: A triple concentric tube heat exchanger when compared to a double tube heat exchanger has improved heat transfer characteristics. The third tube increases the effective area through which heat is transferred. A detailed MATLAB code for the determination of length of a triple concentric tube heat exchanger has been developed. The governing equations are solved using spatial discretization technique. The code can be used to design a triple concentric tube heat exchanger for different mass flow rates and temperature conditions. ANSYS FLUENT analysis has also been carried out for 3m long triple concentric tube heat exchanger. The triple tube heat exchanger is fabricated for experimental analysis
