Direct numerical simulations of turbulent flows over riblet-mounted surfaces are performed to educe the mechanism of drag reduction by riblets. The computed drag on the riblet surfaces is in good agreement with the existing experimental by: The direct numerical simulation of the flow over a sphere is performed. The computations are carried out in the sub-critical regime at Re = (based on the free-stream velocity and the sphere diameter). A parallel unstructured symmetry-preserving formulation is used for simulating the by: A new parallel implicit adaptive mesh refinement (AMR) algorithm is developed for the prediction of unsteady behaviour of laminar flames. The scheme is applied to the solution of the system of partial-differential equations governing time-dependent, two- and three-dimensional, compressible laminar flows for reactive thermally perfect gaseous by: 4. Theory and Numerical Modeling of Turbulent Gas-Particle Flows and Combustion is an excellent book for researchers, designers, instructors, and students interested in this field.
