We have studied a range of pseudo-ternaries derived from the parent compound PrMn2 Ge 2, substituting for each constituent element with a smaller one to contract the lattice. This enables us to observe the magnetoelastic transitions that occur as the Mn-Mn nearest neighbour distance is reduced and to assess the role of Pr on the magnetism. Here, we report on the PrMn2 Ge 2−xSix, Pr1−xYxMn2 Ge 2...

With significant increase of tomographic equipment power, demand for Prediction relative permeability prediction Predicting in porous media from digital image data. In this work, it is predicted three -phase relative permeabilities with co-applying Darcy’s and Stokes equations in two case studies, namely Bentheimer sandstone and Estaillades limestone which their micro-CT data files were downloa...

In designing of condensers, the prediction of pressure drop is as important as the prediction of heat transfer coefficient. Modeling of two phase flow, particularly liquid – vapor flow under diabatic conditions inside a horizontal tube using CFD analysis is difficult with the available two phase models in FLUENT due to continuously changing flow patterns. In the present analysis, CFD analysis o...

Two phase flow in a horizontal tube has widespread applications, particularly in the condensers of refrigeration and air conditioning systems. Pressure drop prediction is especially important for condensers because the local condensing temperature is a function of local pressure, affecting the mean temperature difference in the heat exchanger. In the present analysis, two phase flow is treated ...

Numerical simulation of tracer testing data is conducted based on hydrogeology parameters inferred from pressure interference data. By incorporating both of pressure interferences and tracer testing data, pertinent values of average fracture spacing and rock-matrix permeability can be estimated. Relatively good match of tracer return curves are obtained. It is necessary to assign very small fra...

New dynamic CMOS ternary logic circuits, which can be used to form a pipelined system with the nonoverlapped two-phase clocks, are p r o p e d and investigated. AU the proposed new dynamic ternary gates do not have dc power dissipations and have full voltage swings. For complex ternary logic, a new circuit structure called the simple ternary differential logic (STDL) is also proposed and analyz...
