Large Eddy Simulations of Flow Around a Cylinder with Uncertain Wall Heating

Numerical simulations of the turbulent flow and heat transfer around an array of cylinder are carried out at Reynolds number ReD = 3, 900. The wall heat flux is assumed to be uncertain and characterized by highest variance in the stagnation point region. Simulations are carried out using a novel uncertainty propagation scheme, the hybrid stochastic projection method. This technique combines the...

Effective eddy viscosities in implicit large eddy simulations of turbulent flows

Solving Navier-Stokes equations using monotone algorithms often produces results that are consistent with the dynamics of high Reynolds number turbulence despite formally insufficient numerical resolution to capture all physically relevant scales of motion. It is frequently argued that the truncation error of a numerical scheme provides a mechanism for the energy dissipation and serves as an im...

Comparison of Solution Algorithm for Flow around a Square Cylinder

Numerical accuracy, numerical stability and calculation time are all important factors in the computational fluid dynamics. In this study, we compare two solution algorithms, the Simplified Marker and Cell (SMAC) method in the MAC-type methods and the Semi-Implicit Method for Pressure-Linked Equation (SIMPLE) algorithm in the SIMPLE-type algorithms, with respect to flow around a square cylinder...
