Large eddy simulations of a buoyant plume above a heated horizontal cylinder at intermediate Rayleigh numbers

Soret driven convection in a colloidal solution heated from above at very large solutal Rayleigh number.

Convection in a colloidal suspension with a large negative separation ratio psi is studied experimentally by heating from above. Shadowgraph observations at very large solutal Rayleigh numbers Rtilde; are reported as a function of time. Fast relaxation oscillations are reported for the root mean square value of the shadowgraph intensity. While pure fluids exhibit a transition to turbulent conve...

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...
