This papers describes a computer environment that supports the simultaneous electrical and thermal interactions at device and chip level. A circuit simulator and a finite element thermal simulator are coupled through an application program interface that synchronizes the transfer of information between two simulators. Temperature dependent thermal conductivity of silicon is taken into account b...

Membrane distillation has the potential to concentrate solutions to their saturation level, thus offering the possibility to recover valuable salts from the solutions. The process performance and stability, however, is strongly dependent upon the features of membranes applied. In addition, several other parameters, membrane thickness and thermal conductivity significantly affect the process per...

In this investigation, the performance of an existing heating system of a residential building incorporated with an array of solar thermal collectors was studied. For this purpose, transient systems simulation program model was assembled to estimate the hour-by-hour performance of the existing and the system equipped with the solar thermal collectors in terms of the provided space air condition...

The concept of oxygen- and capacity-dependent thermal tolerance in aquatic ectotherms has successfully explained climate-induced effects of rising temperatures on species abundance in the field. Oxygen supply to tissues and the resulting aerobic performance characters thus form a primary link between organismal fitness and its role and functioning at the ecosystem level. The thermal window of p...

Introduction: In the present experimental investigation, the thermal and electrical performances of a photovoltaic/thermal system equipped with a sheet-and-grooved serpentine tube collector are investigated. The water-magnetite nanofluid is used as the heat transfer fluid. The effect of nanoparticle volume concentration (0-1%), nanofluid mass flow rate (10-40 kg/h) and groove pitch (0, 0.54 an...

Let us know how access to this document benefits you. Abstract As electronic packages and their thermal solutions become more complex the reliability margins in the thermal solutions diminish and become less tolerant to errors in reliability predictions. The current method of thermally stress testing thermal solutions can be over or under predicting end of life thermal performance. Benefits of ...

Varied harsh climatic conditions in different areas of Iran calls for researching different vernacular architectural methods used to gain thermal comfort with the least consumption of energy. The study of vernacular architecture strategies can provide some solutions for contemporary design. This study uses field measurements to analyze the thermal performance of shavadoons (a kind of undergroun...

In the present study, the effect of nano Al2O3 and nano graphene ceramic additives in optimizing performance and improving thermophysical properties of aircraft anti-icing/de-icing fluids was investigated. Nanoparticles were characterized by TEM, SEM and XRD methods. The thermal conductivity, surface tension and dynamic viscosity of the hybrid nanofluids were experimentally assessed for tempera...

In order to keep and improve the position of thermal power generation companies in the competitive market, performance evaluation is necessary. BSC is one of the most efficient performance evaluation models. In this model, there are two assumptions of equal weights of perspectives and equal weights of performance evaluation indicators, which are not necessarily true in real-world problems. BWM ...

abstract: â in this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13x zeolite in a fixed-bed adsorption tower which is used to capture co2 from both humid and dry nitrogen stream under industrial conditions. the results show that the performance of amine-grafted adsorbent and 13x zeolite is almost the same in the dry ...
