Three-dimensional convection flow adjacent to inclined backward-facing step
Simulations of three-dimensional laminar forced convection adjacent to inclined backward-facing step in rectangular duct are presented to examine effects of step inclination on flow and heat transfer distributions. The step height is maintained as constant while its inclination angle is changed from 15 to 90 . The inlet flow is hydrodynamically steady and fully developed with uniform temperatur...
متن کاملAssessment of Turbulence Models for Turbulent Flow over Backward Facing Step
Predication of reattachment length of separated shear layers in low Reynolds number turbulent flow is a challenging task to evaluate the capabilities of different turbulence models, especially for MEMS applications. Physical significances of backward facing step and its industrial applications were discussed. Flow analysis of backward facing step in 2D as well as in 3D were carried out by using...
متن کاملNumerical simulation of laminar to turbulent nanofluid flow and heat transfer over a backward-facing step
This paper presents a numerical study of heat transfer to turbulent and laminar Cu/water flow over a backward-facing step. Mathematical model based on finite volume method with a FORTRAN code is used to solve the continuity, momentum, energy and turbulence equations. Turbulence was modeled by the shear stress transport (SST) K–x Model. In this simulation, three volume fractions of nanofluid (0%...
متن کاملTurbulent Flow over a Backward Facing Step Using Penalty and Equal-order Methods
Two-dimensional steady incompressible turbulent flow over a backward-facing step was calculated using equal-order and penalty function finite element methods. The standard k-ε turbulence model with wall functions was applied. Results from both of the methods for pressure-velocities coupling look pretty similarly to each other. The greatest discrepancy was observed for the velocity vector plots ...
متن کاملDirect numerical simulation of turbulent flow over a backward-facing step
h = 9000. The discretisation is performed using a spanwise periodic spectral/hp element method. The inlet flow has turbulent velocity and pressure fields that are formed by a regenerating channel segment upstream of the inlet. Time and spanwise averages show secondary and tertiary corner eddies in addition to the primary recirculation bubble, while streamlines show a small eddy forming at the d...
