We report results from analog laboratory experiments, in which a large-scale flow is imposed upon natural convection from a hot boundary layer at the base of a large tank of corn syrup. The experiments show that the subdivision of the convective flow into four regions provides a reasonable conceptual framework for interpreting the effects of large-scale flow on plumes. Region I includes the are...

Present study explores the effect of Hall current, non-linear radiation, irregular heat source/sink on magnetohydrodynamic flow of Casson nanofluid past a nonlinear stretching sheet. Viscous and Joule dissipation are incorporated in the energy equation. An accurate numerical solution of highly nonlinear partial differential equations, describing the flow, heat and mass transfer...

the problem of combined heat and mass transfer of an electrically conducting fluid in mhdnatural convection adjacent to a vertical surface is analyzed, taking into account the effects of ohmic heatingin the presence of suction or injection. an approximate numerical solution for the steady laminar boundarylayerflow over a wall of the wedge in the presence of species concentration and mass diffus...

in this study, the experimental analysis on the bare hull resistance coefficient of submarine at snorkel depth is represented. the experiments are conducted in marine laboratory of admiral makarov university. the results are presented for surface condition and snorkel condition. snorkel depth is regarded equal to one diameter of submarine hull beneath the water surface as usual in submarines. p...

A new dynamical subgrid model for turbulent flow in the surface layer of the planetary boundary layer is presented. In this formulation, the flow is decomposed into small (subgrid) and large (resolved) scales in the spirit of large-eddy simulation. The subgrid model, however, is derived directly from the governing equations and involves no adjustable parameters. The evolution of the small scale...
