analyses and thermal infrared channels 4 and 5 NOAA- AVHRR images. This research was carried out in Lut Desert located in center of sub-tropical divergence dominant in' Iranian plateau. The physical and thermal properties of the various desert surfaces have been determined using correlation relationships between the desert variables including: dark sand, normal sand, marl, saline soil, soil dep...

Nanofluids are the heat transfer fluids having remarkable thermal properties. The paper presents the experimental analysis of thermal conductivity, density, specific heat and viscosity of multiwalled carbon nanoparticles dispersed in water at various temperatures and particle concentrations. To examine the forced convection heat transfer of Multiwalled Carbon Nanotubes (MWCNT)-water nanofluid, ...

one of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. in this paper, the authors have studied thermal behaviour for schiff base ligand and their synthesized cobalt, nickel complexes. in this method, the sample is opposed to a controlled temperature change and its physical properties. here we studied melting point and tg...

Conducting polymers, because of their special properties, are used to introduce conductive polymeric composites. Also, clays have recently been used for preparation of polymer composites with enhanced mechanical and thermal properties. The aim of this work is to study the synergetic effect of the co-presence of conducting polyaniline and montmorillonite in the polyethylene matrix. Polyethylene ...

Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...

Thermal buckling behavior of functionally graded Euler-Bernoulli beams in thermal conditions is investigated analytically. The beam with material and thermal properties dependent on the temperature and position is considered. Based on the transformed-section method, the functionally graded beam is considered as an equivalent homogeneous Euler-Bernoulli beam with an effective bending rigidity un...

to design equipment and facilities to dry, preserve and process pomegranates, it is necessary to know their specific heat and thermal conductivity. the objectives of this study were to determine the specific heat and thermal conductivity of pomegranates and develop mathematical estimation models for them. the effects of moisture content (15-75% w.b.) and temperature (5-20°c) on the thermal prop...

Results of electro-thermo-elastic analysis of a functionally graded thick-walled spherical shell made of temperature dependent materials are presented in this article. All material properties are assumed temperature-dependent and also are graded along the thickness direction based on power function. Temperature dependency is accounted for all material properties including, thermal, mechanical a...
