the effect of pulse electric field on mass transfer in sugar beet cossettes with different thicknesses were investigated and compared with traditional thermal processing. two kinds of sugar beet cossettes 3±0.5 cm and 2±0.5 thicknesses with 3–5 cm long subjected to pulse electric field (3kv, 8 µf, and 20 pulse) and compared with heat treated samples (80ºc for15 minutes) as conventional thermal ...

in this study, mass transfer coefficients (mtc’s) of natural gas components during hydrate formation are reported. this work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...

in the present paper, the flow and heat transfer of two types of nanofluids, namely, silver-water and silicon dioxide-water, were theoretically analyzed over an isothermal continues stretching sheet. to this purpose, the governing partial differential equations were converted to a set of nonlinear differential equations using similarity transforms and were then analytically solved. it was found...

since the energy analysis considers the quantity of energy, it cannot show the performance of the cooling tower. therefore, in order to optimize the performance of the tower and also the process which the cooling tower is a part of it, it is necessary to analyze the energy and exergy of the tower simultaneously. in this paper, the energy and exergy of one of the cooling towers of khuzestan stee...

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...

Results of permeation experiments involving finite dose diffusion c :Ils with hairless mouse skin as the membrane indicate that neither intact liposome; nor the phospholipid of which they are comprised diffuses across the skin. Lipoph lit drugs like progesterone and hydrocortisone, which are intercalated within th: bilayer structure of the phospholipid in miltilamellar liposomes. seem to pass t...

The aim of this paper is to investigate the effect of variable viscosity on free convective heat and mass transfer from a horizontal plate embedded in a saturated porous medium. The governing equations of continuity, momentum, energy and concentration are transformed into non linear ordinary differential equations using similarity transformations and then solved by using Runge – Kutta – Gill me...
