dc.description.abstract |
This study presents the LES (large eddy simulation) of forced convection in laminar and two dimensional turbulent flows
when the flow reaches the steady state. The main purpose is the evaluation of a developed numerical methodology for the simulation of
forced convection flows at various Reynolds numbers (100 ≤ ReH ≤ 10,000) and for a fixed Prandtl number (Pr = 1.0). The hexahedral
eight-node FEM (finite element method) with an explicit Taylor-Galerkin scheme is used to obtain the numerical solutions of the
conservation equations of mass, momentum and energy. The Smagorinsky model is employed for the sub-grid treatment. The
time-averaged velocity and temperature profiles are compared with results of literature and a CFD (computational fluid dynamics)
package based on finite volume method, leading to a highest deviation of nearly 6%. Moreover, characteristics of the forced convection
flows are properly obtained, e.g., the effect of the Reynolds number over the multiplicity of scales. |
