thermal conductivity is an important property of juices in the prediction of heat- and mass-transfer coefficients and in the design of heat- and mass-transfer equipment for the fruit juice industry. an artificial neural network (ann) was developed to predict thermal conductivity of pear juice. temperature and concentration were input variables. thermal conductivity of juices was outputs. the op...

fluid properties with constant improvement in efficiency have been noticeable as important criteria in drilling operation. the main drilling fluid properties highly depend on utilization of new polymers with high efficiency in drilling fluid composition. in this paper, the performance of a new polymer, called partially hydrolyzed polyacrylamide polymer (phpa), is studied which has recently ente...

effect of nanosilver (ns) on the heat-transferring rate to the core section of medium density fiberboard (mdf) mat was studied here. a 400 ppm aqueous nanosilver suspension was used at three consumption levels of 100, 150, and 200 ml/kg, based on the weight of dry wood fibers; the results were then compared with the control mdf panels. the size range of nanosilver was 30-80 nm. results showed t...

Thermal analysis (DSC: Differential Scanning Calorimetry and TGA: Thermogravimetric Analysis) of SEBS blends have been studied in this paper. SEBS blends were made using two transparent SEBS commercial grades with extreme hardness values. The first thermal property determined in SEBS blends was the evaluation of the thermal degradation at high temperatures (DSC). Another thermal property of the...

thin bonded films have many applications in antireflection and reflection coating, insulating and conducting films and semiconductor industries. thermal conductivity is one of the most important parameter for power packaging since the thermal resistance of the interconnections is directly related to the heat removal capability and thermal management of the power package. the defects in material...

Thermal property is the important material property for engineering and analysis of insulating materials. In this study, thermal conductivities of insulating materials are determined and compared with the literature values. Lee’s and Charlton’s apparatus is used to measure this property of insulating materials by steady state technique. This apparatus gives more precise result for insulators th...
