A full 3-dimensional (3D) conjugate heat transfer model has been developed to simulate the heat transfer performance of siliconbased, parallel microchannel heat sinks. A semi-normalized 3-dimensional heat transfer model has been developed, validated and used to optimize the geometric structure of these types of microheat sinks. Under a constant pumping power of 0.05 W for a water-cooled microhe...

[1] Interphase mass transfer in variable aperture fractures occurs in many problems where two immiscible fluids are present, such as dissolution of dense nonaqueous phase liquids into groundwater, dissolution of CO2 in deep saline aquifers, and evaporation of trapped water by flowing gas during natural gas production. Typically, one fluid is entrapped by capillary forces and resides in immobili...

at the beginning of this paper, design and manufacturing stages of the 3 degree of freedom test stand for a remotely piloted helicopter is described, in which the helicopter is able to rotate about its three primary accesses. in the next parts the dynamical model of the rph in the yaw channel is presented and lateral transfer function of rph (yaw channel) is extracted by performing several test...

An analytical investigation is made to determine the heat and mass transfer mechanism of non-isothermal highly viscous uid in a long narrow porous channel. The walls channel are maintained at same temperature. mathematical model developed by using continuity, momentum, energy diffusion equations. Analytical solutions establish get expressions velocity eld, pressure distribution, ow rate, wall s...

Mathematical models were used in the investigation of mass transfer magnetic drug on lipoprotein during mhd blood an arterial channel. The non-linear partial differential equations changed into linear and then solved analytically to obtain exact solutions. numerical results obtained through plots showing parameter variations their effects focus study. With help graphs parameters such as Grashof...
