WebIn this paper, a Computational Fluid Dynamics (CFD) analysis has been carried out to study the effect of annular fins for oil flow in a horizontal tube. The design parameters are fin height and fin spacing under forced convection conditions and flow is taken as laminar flow. The number of fins used is six, fin height is taken as 40mm and 60 mm ... WebApr 13, 2024 · Linear stability analysis of a combined convective flow in an annulus is performed in the paper. The base flow is generated by two factors: (a) different constant wall temperatures and (b) heat release as a result of a chemical reaction that takes place in the fluid. The nonlinear boundary value problem for the distribution of the base flow …
