Abstract: The performance of a double pipe heat exchanger is analyzed using Response Surface Methodology (RSM) with various input parameters namely Reynolds number, twisted ratio(y/w) and concentration of SiO2 nanofluid of the output response the overall heat transfer coefficients of the double pipe heat exchanger. The experimental design is developed based on Box - Behnken design method. The influence of vital input parameters and interaction among them are investigated using analysis of variance (ANOVA). optimum value of the overall heat transfer coefficients is 2732.59(w/m2.k) when the Reynolds number ut is 19999.42, concentration(0.5%w) and twisted ratio(y/w) 5.87. In the desirability function approach, the value of desirability was 0.937 for the RSM model very close to The predicted RSM model is found to be capable of predictive overall heat transfer coefficients of double pipe heat exchanger.
