In modeling transport within naturally heterogeneous aquifers, it is usually assumed that the transport equations valid at local scales can also be applied at larger scales. At larger scales, the heterogeneous domain is represented by an equivalent homogeneous medium. Convergent-flow tracer tests constitute one of the most frequently used field tests to estimate effective input parameters of eq...

This study investigates the effect of homogeneous and heterogeneous peer interaction on the development of Iranian EFL learners’ writing skill. Sixty female students of TEFL participated in the study. The participants were divided into two groups based on their English proficiency test scores. The homogeneous group consisted of 14 participants paired with partners with similar English proficien...

Numerical simulations of the small bubble-big bubble-liquid three phase heterogeneous flow in a square cross-sectioned bubble column were carried out with the commercial CFD package CFX-4.4 to explore the effect of superficial velocity and inlet dispersed phase fractions on the flow patterns. The approach of Krishna et al. (2000) was adopted in the Euler-Euler framework to numerically simulate ...

The impacts of magnetic field dependent viscous fluid is explored between squeezing plates in the presence homogeneous and heterogeneous reactions. unsteady constitutive equations heat mass transfers, modified Navier-Stokes, reactions are coupled as an system ODE. appropriate solutions established for vertical axial induced transformed momentum well MHD pressure torque exerted on upper plate, d...

Abstract Background The cylindrical profile model (CPM) is commonly used to convert the load–displacement measurement from axis-symmetric compression test (ACT) flow curve. ignores barrelling of sample which results in serious curve distortion and underestimation effective stress strain. To minimize these, a new solution ACT with heterogeneous deformation proposed this work as an alternative CP...
