Abstract
Abstract
This experimentation aims to study Nusselt number (Nu) and Friction factor (f) deriving from the forced flow of fluid inside a circular pipe under a uniform heat flux condition. Porous media used in this study is made of stainless-steel wire mesh 304 which has the number of pores per inch (PPI) of 8. Reynolds number (Re) ranges from 3000 – 15000. Distance between two plates of wire mesh (p), ranges from 10-50 mm. The results of the experiment indicate that the Nu figure tends to be higher when there is a rise in Re and a decrease in length of p, resulting in an increase in mass of material. The increasing mass of material enables it to store a large quantity of energy from hot air causing heat to be transferred toward the pipe wall in a higher rate. The value f tends to decline when the Re and p grow up. This phenomenon rather conforms to the general principles of nature, namely that a barrier against the flow will lead to a higher friction factor (f). The Performance Evaluation Criteria (PEC), recorded across the whole Reynolds number range, reaches a maximum where the p is 40 mm since the ratio of Nu to f is the most appropriate figure.
