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...

This work describes a novel optothermal method for electrokinetic concentration and manipulation of charged analytes using light energy, for the first time. The method uses the optical field control provided by a digital projector to regulate the local fluid temperature in microfluidics. Thermal characteristics of the heating system have been assessed by using the temperature-dependent fluoresc...

The prediction of entropy generation with a thermal and exponential space dependent heat source unsteady flow over rotating disk is the artifact paper. For specific physical model, non-Newtonian fluids like Oldroyd-B within EMHD fluid encrypted. Also, mechanism cobalt tantalum nanoparticles in blood employed. proper self-similarity variables are used to convert non-linear PDE system equations i...

The heat exchanger in a heat pump can be modelled by the zero Mach-number limit of the Euler equations of compressible fluid flow. This system turns out to be a coupled hyperbolic/parabolic equation with coupled, time-dependent boundary conditions. Using the theory of abstract differential-algebraic equations it is shown that the frozen coefficient system has ADAE index 1. Moreover, the much st...

The effect of temperature-dependent viscosity on heat transfer over a continuous moving surface with variable internal heat generation in micropolar fluids is studied. The fluid viscosity is assumed to vary as inverse linear function of temperature. The governing equations are transformed into dimensionless forms using the stream function and suitable variables then solved numerically using the...
