Gamal M. Chemical entropy generation and magnetohydrodynamic effects on the unsteady heat and fluid flow through a porous medium have been numerically investigated. The entropy generation due to the use of a magnetic field and porous medium effects on heat transfer, fluid friction, and mass transfer have been analyzed numerically.

Entropy generation through heat and fluid flow

This article deals with the investigation of three-dimensional axisymmetric steady flow of micropolar fluid over a rotating disk in a slip-flow regime. Further, the generation of entropy due to heat transfer and fluid friction is identified. It is noticed that the entropy generation can be decreased and controlled in the presence of slip. The anisotropic slip has vital characteristics and it has a great influence on the flow field and heat transfer. The impact of some important parameters on velocity profiles, angular velocity microrotation and energy distribution is discussed and illustrated through graphs and tables. The effects of physical parameters on the entropy generation and Bejan numbers are also presented graphically. In addition, the most favorable agreement is observed among the results of the present study and those of the earlier studies.

This consideration highlights the belongings of momentum, entropy generation, species and thermal dissemination on boundary layer flow BLF of Casson liquid over a linearly elongating surface considering radiation and Joule heating effects significant. Transportation of thermal and species are offered by using the temperature-dependent models of thermal conductivity and mass diffusion coefficient.

Entropy Generation in a Rotating Couette Flow with Suction/Injection

This study aims to investigate a three-dimensional computational modelling of free convection of Al 2 O 3 water-based nanofluid in a cylindrical cavity under heterogeneous heat fluxes that can be used as a thermal storage tank. Effects of different heat flux boundary conditions on heat transfer and entropy generation were examined and the optimal configuration was identified. The simulation results for nanoparticle NP volume fractions up to 4 per cent, and Rayleigh numbers of 10 4 , 10 5 and 10 6 were presented. The results showed that for low Ra 10 4 the heat transfer and entropy generation patterns were symmetric, whereas with increasing the Rayleigh number these patterns became asymmetric and more complex.

 Ты прав - и так и должно быть! - сурово отрезала Сьюзан.  - Если бы ты не нашел черный ход в Попрыгунчике, мы могли бы взломать любой шифр, вместо того чтобы полагаться на ТРАНСТЕКСТ. - Если бы я не нашел черный ход, - сказал Хейл, - это сделал бы кто-то .

Он очутился в огромной комнате - бывшем гимнастическом зале. Бледно-зеленый пол мерцал в сиянии ламп дневного света, то попадая в фокус, то как бы проваливаясь. Лампы зловеще гудели. На стене криво висело баскетбольное кольцо. Пол был уставлен десятками больничных коек.

 Двухцветный? - изумился Беккер.  - Попробую отгадать… из-за прически. - Верно, Шерлок Холмс.
