In this study, a new method for joining aluminum tubes in subsurface structures using steel converting and aluminum welding are presented and reviewed. But near the weld area is under high thermal cycle and will cause residual stresses in heat affected zone. Therefore for assessment of proposed connection from the perspective of residual stress by using the finite element method welding of tu...

the highest temperatures of the world are recorded in dry and warm climates. this can especially be observed in deserts, where vegetations and soil moisture are very low. as a result, the soil surface receives high thermal energy and its temperature rises up. the lut desert has the above characteristics, making it a suitable environment to prepare land surface temperature (lst) models. objectiv...

́ Abstract. A new modeling approach for steady-state fluid flow analysis of networked thermal systems with temperature control devices is proposed in this paper. The problem of temperature control is crucial for the design and analysis of such thermal systems as air conditioning systems of data centers, for their control as well as providing the best data center performance and reliability. It i...

The present paper discusses the development of a performance model of power generation system of a thermal plant for performance evaluation using Markov technique and probabilistic approach. The study covers two areas: development of a predictive model and evaluation of performance with the help of developed model. The present system of thermal plant under study consists of four subsystems with...

In this article some of the important techniques in electromagnetic (EM) and thermal dosimetry are reviewed. Three major areas are discussed: modeling power deposition and estimation of EM energy absorbed by tissues exposed to EM radiation, electrical-thermal modeling for thermal therapy with various models of heat transfer in living tissues, and thermal dosimetry using invasive and noninvasive...

in this paper, fourteen mt stations along a profile perpendicular to the main geological structure were used in order to identify the geology of sabalan geothermal field including the extension of the surface cap-rock and clay-cap layers. the mt data collected between 1-8192 hz is of useful quality and provides good control on the surface layers in many areas. it means that reliable modeling sh...

Multi-scale model for response of the bi-material “thermostat,” consisting of a single unidirectional lamina of carbon/epoxy and an uncured layer of neat diglycidyl ether of bisphenol F (DGEBF) with curing agent, diethyltoluenediamine (DETDA), is developed in order to measure thermal strains during a prescribed, but arbitrary thermal history. Molecular modeling simulations provided the elastic ...
