The paper presents a methodology for simulating the static and dynamic performance of integrated circuits in the presence of electro-thermal interactions on the integrated circuit die. The technique is based on the coupling of a finite element method (FEM) program with a circuit simulator. In difference to other known simulator couplings a time step algorithm is used. Its implementation into si...

An overview of electro-thermal modeling of microsystems is presented. We consider the most important coupling between thermal and electrical phenomena, and then focus on the industry’s central concern, that of Joule heating. A description of different solution approaches for the heat transfer partial differential equation, which constitutes the central part of electro-thermal simulation, is giv...

Power has become the primary design constraint for systems ranging from server computers to handhelds. As semiconductor technology scales down, leakage power becomes significant. Leakage power is exponentially dependent on temperature. Therefore, future design studies call for temperature-aware power modeling and coupled power and thermal management due to the temperature dependence of leakage ...

the micro-segregation in binary al-cu alloys containing 2.2, 3.7, and 4.8 wt.% copper was investigated by differential thermal analysis (dta) and numerical modeling. for this purpose, the alloys were melted using a dta furnace with the capability of quenching samples during solidification. the melted samples were cooled at 0.008 and 0.083 k/s and subsequently quenched from predetermined tempera...

Common heat transfer fluids such as water, ethylene glycol, and engine oil have limited heat transfer capabilities due to their low heat transfer properties. Nanofluids are suspensions of nanoparticles in base fluids, a new challenge for thermal sciences provided by nanotechnology. In this study, we are to optimize and report the effects of various parameters such as the ratio of the thermal co...

information on the thermophysical properties of the iranian ultrafiltrated (uf) white cheese is very limited. in this research, those thermal properties determined experimentally were thermal conductivity, specific heat, density and water activity. the thermal conductivity and specific heat of iranian ultrafiltrated white cheese (iufwc) ranged from 0.447 to 0.480 w m-1 °c-1 and from 3.871 to 4....
