the present study deals with the analysis of the effects of radiative heat transfer of micropolar fluid flow over a porous and stretching sheet in the presence of magnetic field. the dynamic viscosity and thermal conductivity coefficient have formulated by temperature-dependent relations to obtain more exact results. the flow is supposed two-dimensional, incompressible, steady and laminar and t...

drying characteristics of quercus were determined experimentally as a function of temperature, air velocity, and variety (quercus persica and quercus libani). in order to estimate and select a suitable drying curve, five different thin layer drying models were fitted to the experimental data. experiments were performed at the air temperatures of 50, 60 and 70°c. at each temperature level, two a...

analysis of the flow passing cylindrical obstacles is one of the basic issues in fluid dynamics and is of great importance. many surveys have been conducted to investigate the velocity field in potential and viscous flows, as a basis for finding pressure field, and investigation of forces exerted by fluid on obstacles such as uplift and drag forces in different flow regimes. since the nature of...
