In the present era where energy demands are growing everyday it has become very important to capture every available energy from the hot source and utilize it for the process with minimum wastage. With this view, the combined serial two shell pass shell and tube heat exchanger (CSTSP) concept had been put forward and simulated using Fluent. Though the novel model of the heat exchanger has a hig...

k thermal conductivity, W/mK An analytical model is developed for predicting constriction and spreading resistances associated with heat transfer from various electronic components under different modes of cooling. The model assumes a heat source in contact with a larger cold plate which is in turn cooled with a convective heat transfer coefficient specified over the sink surface. Unlike existi...

Deep borehole heat exchanger is promising and competitive for seasonal storage in the limited space underground with great efficiency. However, performance of essentially deep reaching kilometers was seldom studied. In addition, previous research rarely achieved comprehensive assessment its thermal due to storage. Insight into complicated transfer characteristics during whole process prior char...

The main goal of the current research is to investigate numerical computation Ag/Al2O3 nanofluid over a Riga plate with injection/suction. energy equation formulated using Cattaneo–Christov heat flux, non-linear thermal radiation, and sink/source. leading equations are non-dimensionalized by employing suitable transformations, results achieved MATLAB bvp4c technique. fluctuations fluid flow tra...

abstract:a mathematical model for the performance prediction of an industrial glass furnace with six ports on each side was developed. this model comprises of two main sub-models for the combustion chamber and glass-melting tank. the first sub-model consists of the models for the combustion and the heat transfer model including, radiation, convection and conduction. the fuel combustion in atmos...

Organic Rankine Cycle (ORC) enables power generation from lowto medium temperature heat sources. In an ORC, the organic medium shows different performances for different heat source temperatures. For a range of heat source temperatures, one temperature can be always identified corresponding to the best thermal match between the heat transfer fluid and working fluid. This temperature is defined ...

This paper presents a 3D boundary element model (BEM), formulated in the frequency domain, to simulate heat diffusion by conduction in the vicinity of 3D cracks. The model intends to contribute to the interpretation of infrared thermography (IRT) data results and to explore the features of this nondestructive testing technique (NDT) when it is used to detect and characterize defects. The defect...

We consider the zonal mean circulation on an equatorial &plane and obtain analytic solutions for small-amplitude disturbances in response to sources of heat and momentum. The effect of dissipation is roughly approximated by using assumed constant drag and radiative damping terms. We apply the model to the tropospheric zonal winds, temperatures, and meridional circulation to give simple insights...
