Abstract

A Direct numerical simulations (DNS) is carried out to study the highly three-dimensional flow field around a jet coming out of a stack and interacting with the cross-flow passing it. The major objective of the study is to assess the effect of shear strength of inlet velocity on the wake behavior and structures for elevated jets in cross-flow (EJICF). All the simulations are carried out for a Reynolds number of 250 based on the averaged inlet velocity and width of the stack and the blowing ratios considered are 0.5, 1.0 and 1.5. Effect of shear strength (0.025, 0.050 and 0.075) of inlet velocity is studied by solving the incompressible unsteady 3-D Navier-Stokes equations using a second order discretization for space and time. The solution algorithm is based on MAC method. The dynamics of flow associated with the flow field, like different wakes zones present in the flow are discussed with respect to the shear strength of free stream velocity. The vortical structure associated with EJICF is also studied.
