چکیده | ||
This research investigates the influence of wall proximity on convective heat transfer and fluid flow characteristics in a two-dimensional laminar regime around a circular cylinder. Six unique configurations, comprising various combinations of nearby and distant walls, are examined through numerical simulation. Assumptions related to incompressibility, viscosity, transiency, and Newtonian behavior inform the underlying fluid mechanics model. Governing equations encompass conservation principles for mass, momentum, and thermal energy. Applying the finite volume approach within a commercial computational framework facilitates numerical solutions for each test condition. A notable outcome indicates how the spacing between the cylinder and adjacent surfaces affects the drag force coefficient, revealing marked differences based on cylinder placement – either nestled between two stationary planes or situated near a singular bounding wall. Increasing interlayer frictional forces instigate reductions in fluid velocity, leading to diminished drag coefficients at higher Reynolds numbers. Moreover, implementing comparative analyses elucidates the substantial enhancements in the Strouhal number (by 44%), the Nusselt number (by 14%), the drag coefficient (by 108%), and the lift coefficient (by 112%) experienced by a confined cylinder suspended between two quiescent plane surfaces, contrasted against an isolated cylinder devoid of neighboring constraints. Collectively, these observations accentuate the significance of the particular arrangement wherein the cylinder exists equidistant between two motionless walls. | ||
