الملخص الانجليزي
The paper investigated forced convective fluid flow and heat transfer in gravitationally oriented circular ducts with equi-spaced internal longitudinal fins for the purpose of augmenting heat transfer in heat exchangers of circular cross-section. Navier–Stokes equation of motion and energy transport equation were adopted as the governing equations for the fluid flowing in the geometry. The governing equations were non-dimensionalized using certain defined transformation parameters. A computational algorithm was developed based on the finite difference scheme for the normalized governing equations. A Quick-BASIC program was developed for the implementation of the scheme. The computed results show that between 00-150 pipe inclinations, there is a rapid increase in heat transfer enhancement which slowly increases towards 750 inclination and remains almost a plateau up to the vertical position of the pipe. It was discovered that although increased fin height above H = 0.2 increases the heat transfer surface area: parameters of fluid volume and flow velocity are adversely affected and therefore, any protrusion beyond H = 0.2 is a waste of material and resources
