The amount of energy lost during any irreversible process is called entropy. The focus of this paper is on how to reduce this energy loss in order to improve the capacity of our system, especially in the presence of planktonic microorganisms. To understand the flow physics associated with bolus formation and the impact of reverberation on the micro vessel, a 3D computational fluid dynamic analysis is performed. The effects of binary chemical interaction with nonlinear mixed convection and Arrhenius activation energy are considered in the present analysis. The complexity of the system was achieved through a numerical approach based on the concepts of small Reynolds number and large wavelength. The resulting nonlinear coupled differential equation system is solved numerically using the built-in command in MATHEMATICA (ParametricNDSolve). Some of the investigation's findings are the entropy profile has been improved for incremental values of Hartmann number and Brinkmann number whereas the axial velocity shows a downward trend for the highest values of the Hartmann number and the material parameter "A". The improvement in the flow, heat, and mass transmission properties of hypoxic tumor regions, will provide developing in drug carrier uses in hypoxic carcinoma regions.
The radial power transmission resulting from a particle beam of parabolic (quadratic) transverse charge distribution have been studied theoretically. The particle beam is moving at constant speed down a resistive cylindrical pipe of finite wall thickness. The wave equations for the electromagnetic fields induced by the beam motion inside the cylindrical pipe have been derived and solved. The coefficient of radial power transmission through the beam-pipe wall have been obtained analytically and then analyzed numerically for different beam energies, different wall conductivities and different wave mode frequencies. The radial power transmission is found to increase with increasing beam energy, to decrease with increasing wall conductivity and it is higher for the wave modes of lower frequencies.
