An explicit finite-difference scheme is presented for solving the two-dimensional Biot equations of poroelasticity across the full range of frequencies. The key difficulty is to discretize the Johnson-Koplik-Dashen (JKD) model which describes the viscous dissipations in the pores. Indeed, the time-domain version of Biot-JKD model involves order 1/2 fractional derivatives which amount to a time ...

In the field of mobile machine research is mainly focused on solutions to reduce energy dissipations and fuel consumptions being these machines equipped with Diesel engines. This paper presents a solution for improving performance traditional Load sensing flow sharing circuit. The concerns insertion signal conditioner (LSc), developed by Walvoil S.p.A., that permits dynamically change pressure ...

In this work, we have studied Joule heating in carbon nanotube based very large scale integration (VLSI) interconnects and incorporated Joule heating influenced scattering in our previously developed current transport model. The theoretical model explains breakdown in carbon nanotube resistance which limits the current density. We have also studied scattering parameters of carbon nanotube (CNT)...

The thermosphere is subject to additional electric and magnetic forces, not important in the middle and lower atmosphere, due to its partially ionized atmosphere. The effects of charged particles on the neutral atmospheric dynamics are often parameterized by ion drag in the momentum equations and Joule heating in the energy equation. Presented in this paper are a set of more accurate parameteri...

Abstract Electromagnetic high-temperature therapy is popular in medical engineering treatments for various diseases including tissue damage ablation repair, hyperthermia, and oncological illness diagnosis. The simulation of transport phenomena such applications requires multi-physical models featuring magnetohydrodynamics, biorheology, heat transfer, deformable porous media. Motivated by invest...

Recent experimental reports indicate that Joule heating can atomically sharpen the edges of chemical vapor deposition grown graphitic nanoribbons. The absence or presence of loops between adjacent layers in the annealed materials is the topic of a growing debate that this Letter aims to put to rest. We offer a rationale explaining why loops do form if Joule heating is used alone, and why adjace...

Joule heating is an inevitable phenomenon for microfluidic chips involving electrokinetic pumping, and it becomes a more important issue when chips are made of polymeric materials because of their low thermal conductivities. Therefore, it is very important to develop methods for evaluating Joule heating effects in microfluidic chips in a relatively easy manner. To this end, two analytical model...
