this work presents the heat transfer characteristics of a new type of porous radiant air heater that operates on the basis of effective energy conversion method between flowing gas enthalpy and thermal radiation. at each layer, the gas and solid phases are considered in non-local thermal equilibrium, and combustion in the porous radiant burner is modeled by considering a non-uniform heat genera...
Objective: To investigate the effect of intravascular heat exchange in saving the lives of patients after cardiopulmonary resuscitation. Methods: The clinical data of a female patient who was given cardiopulmonary resuscitation for 1.67 h in July 2014 in our hospital was retrospectively analyzed. An intravascular heat exchange procedure was performed on the patient to control her body temperatu...
Introduction: Heat stress is caused by many factors such as individual factors, environmental factors, and management factors. Individual risk factors can decrease the heat tolerance, and play an important role in heat stress disorders incidence. The aim of this study was to review individual parameters influencing the thermal stress and review the preceding studies. Material and Method: In ...

Heat exchange belongs to the class of basic thermal processes which occur in a range of industrial technologies, particularly in the energetic, chemical, polymer and rubber industry. The process of heat exchange is often implemented by through-flow heat exchangers. It is apparent that for an exact theoretical description of dynamics of heat exchange processes it is necessary to use partial diff...
