Numerical Analysis of Forced Convection in Novel Cylindrical Oblique Finned Heat Sink

Abstract

In this paper ,forced convection heat transfer of laminar flow through novel cylindrical discrete oblique fin heat sinks were simulated by Computational fluid Dynamics method(CFD).The multi-channel structure was imported  into fluent V 15.0 as a physical model to be simulated. In this paper were going to found various heat transfer rates with respect angles for the entire oblique heat sink. According to the results the average of heat transfer is 1.99W with respect to fin angle at 60⁰. because of the above reason we will get minimum wall temperature and temperature gradient of the oblique heat sink in addition to the we were investigate the various velocities of fluid pressure and Nusselt number, Reynolds number. Lastly the guide lines for optimising cylindrical heat sink structure in different applications were also discussed.
