entropy generation in an unsteady hydromagnetic couette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates in a rotating system have been analyzed. both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient following the newton's law of cooling. a numerical solution for governin...

The presented article addresses the electro-osmotic peristaltic flow of a couple stress fluid bounded in an inclined asymmetric micro-channel. viscous dissipation, Joule heating and chemical reaction effects are employed simultaneously analysis. Heat mass transfer have been studied under large wavelength small Reynolds number. resulting nonlinear systems solved numerically. influence various do...

shape error due to elastic recovery of formed part in unloading known as springback, is one of the most important problems of tool design in sheet metal forming processes. many researches have been performed for proposing an efficient method to decrease or compensate springback error in sheet forming processes. these methods are usually based on iterative finite element algorithms. in this pape...

To investigate hydrodynamic performance of the end cover under different inclined angles, a series of 3-Dimensional geometric models of the end cover with different inclined angles were built by Creo. The maximum inclined angle is 32 degrees and the minimum is 6 degrees. Numerical simulations by solving the Navier-Stokes equation, coupled with the “k-ɛ” turbulence model, were carried out. At la...

Experimental study of natural convection heat transfer inside smooth and rough surfaces of vertical and inclined equilateral triangular channels of different inclination angles with a uniformly heated surface are performed. The inclination angle is changed from 15o to 90o. Smooth and rough surface of average roughness (0.02mm) are used and their effect on the heat transfer characteristics are s...

Vortex shedding from a circular cylinder and from an inclined flat plate is computed with a finite volume CFD code with RNG k-ε turbulence model. The wake behind the circular cylinder consists of two trains of vortices of equal strengths. Dependence of vortex patterns on Reynolds numbers at Re between 10 and 10 is investigated. Flow over the inclined flat plate is asymmetric and unequal charact...

By only sending the parity bits, joint source-channel coding can be natively achieved with lowdensity parity-check codes. However, the code ensemble design of optimal low-density parity-check codes for joint source-channel coding over asymmetric communication channels is difficult. To circumvent such a difficulty, source-channel adaptors is proposed in this paper. By using the source-channel ad...
