Abstract
ABSTRACT The present computational study examines the transient analysis of forced convective flow and heat transfer in a long open channel with an oscillating blade initially placed either horizontally or vertically to investigate the impacts on the heat transfer performance and pressure drop in the channel of the blade's position. For mathematical modeling, the Arbitrary Lagrangian–Eulerian finite element method has been employed to precisely model the moving mesh boundary conditions under various simulation parameters. Simulations are performed for the Reynolds number, Re = 50, and Prandtl number, Pr = 1. The nondimensional maximum linear velocity and oscillating frequency are modified with the values V m = 0.5, 1.0, 2.0, and F c = 0.2, 0.5, 0.8. The results show that…
