Complex heat transfer phenomena (including unsteady state conduction, convection and solidification processes) occur in steel belt conveyer sulfur granulating method. Numerical simulation of this technique is performed via a comprehensive and multifaceted one dimensional model. Since the air situated between the adjacent sulfur pastilles is essentially stagnant, therefore, the surface tempe...

Significant research efforts have been devoted in the past decades to accurately modelling complex heat transfer phenomena within biological tissues. These modeling and analysis assisted a better understanding of intricacies associated factors that affect treatment outcomes hyperthermic therapeutic procedures. In this contribution, we report three-dimensional non-Fourier bio-heat model cardiac ...

Heat transfer characteristics for a laminar fully developed flow in an internally corrugated circular tube with axially uniform heat flux with peripherally uniform temperature are obtained using the method of fundamental solution and the radial basis functions. The internal shape of the tube is modelled by cosine function. The nonlinear governing equation of temperature field problem was conver...

In this paper, the combination of conduction with radiation into a semitransparent medium which includes absorption, emission and scattering has been investigated. In order to Study the conduction in medium, the Non-Fourier heat conduction has been applied. In this model there is a time delay between heat flux and temperature gradient. Also, in contrast with Fourier heat conduction, the speed o...

The Hyperbolic Heat Transfer Equation describes heat processes in which extremely short periods of time or extreme temperature gradients are involved. It is already known that there are solutions of this equation which exhibit a chaotic behaviour, in the sense of Devaney, on certain spaces of analytic functions with certain growth control. We show that this chaotic behaviour still appears when ...

In this work, we derive an analytical solution for heat transfer characteristics of a thermally developing flow of viscoelastic fluids under the application of an electroosmotic force. The walls are subjected to either in isothermal condition or a constant wall heat flux is employed. First, we derive a Helmholtz-Smoluchowski (HS) type slip velocity for the viscoelastic fluids, which is further ...
