A theoretical investigation is performed for studying the flow of heat transfer characteristics of Sakiadis and Blasius flow of magnetohydrodynamic Maxwell fluid with thermal radiation. We also incorporated the Cattaneo-Chirstov heat flux model to control the heat transfer phenomena. Numerical solutions are carried out by using Shooting technique. The effects of various governing parameters on ...

Hydrogen fluoride (HF) has found a wide variety of uses in the chemical process industry. It is used as an alkylation catalyst in the making of high-octane fuel, it provides a fluoride ion source in the electrolytic production of aluminum, and it is also the fluorine source in fluorocarbon manufacture. Intrinsic to the successful design of separation and heat-transfer equipment utilizing HF is ...

This paper modeled heating air of a room through examining free convection in a 3D chamber. The chamber had cold and hot sources with Tc and Th temperatures, respectively. Its other walls were adiabatic. This study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. To conduct the st...

Entropy generation due to viscous incompressible MHD forced convective dissipative fluid flow through a horizontal channel of finite depth in the existence of an inclined magnetic field and heat source effect has been examined. The governing non-linear partial differential equations for momentum, energy and entropy generation are derived and solved by using the analytical method. In addition; t...

An old problem in Isothermal Titration Calorimetry is the accurate characterisation of the instrument, i.e. the determination of the instrumental transfer function. Normally, this calibration is performed electrically or through well known chemical reactions, but the transfer function parameters obtained by both methods generally do not agree: the first method normally yields smaller time const...

A two dimensional deformation due to internal heat source in a thermoelastic solid with microtemperatures under the dependence of modulus of elasticity and thermal conductivity on reference temperature has been studied. A mechanical force of constant magnitude is applied at the free surface of thermoelastic half space. The normal modes technique has been applied to obtain the exact expressions ...

Our physical environment is endowed with unlimited amount of natural and artificial sources of energy at various low exergetic levels which leaves them almost impossible to be thermally utilized at such source states. The thermal upgrading of these low exergetic energy sources could render them amenable to various practical thermal usages. This paper provides a comparative study through simulat...
