this work concerns the peristaltic flow of a williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. the governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. the analytical results are computed with the help of regular perturbation and the numerical result...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...

In tight reservoirs, the rock formations are typically less porous and permeable, which makes it more difficult for hydrocarbons to flow through them. addition length conductivity, height of a fracture is another critical parameter hydraulic fracturing treatments in unconventional tight/shale formations, determines stimulated reservoir volume. If too shallow, volume exposed fluid proppant may n...

In order to ensure the most complete recovery of hydrocarbons and minimize costs in production process, it is necessary control development an oil field, even during production, through various geological technological measures. terms volume additional extracted implementation measures, hydraulic fracturing (HF) operations occupy top positions.
 This paper describes a modified method for a...
