“…g-Jitter gives additional effect on material processing in microgravity environment which interact the density gradient and result in both fluid flow. It is important to understand the effect of g-jitter to design and maintaining the cooling board of a system to prevent such overheating cause problem like explosion in practical application (2). Therefore, the main objective of this research is to investigate the effect of Newtonian heating and g-jitter towards mixed convection flow between two parallel vertical plates motivated by Hayat (3).…”

This article deals with the mixed convection flow between two vertical parallel plates with the effect of g-jitter. Newtonian heating is considered on the left wall of the plate. The governing equations of heat and mass transfer are modelled in the Cartesian coordinate system with the effect of g-jitter. Non-dimensional variables are used to transform the governing equations together with the boundary layer condition. Separation of variables method are applied to provide the exact analytical solutions for the velocity, temperature and concentration profiles. The obtained solutions are computed to produce the graphical results. It is showed that due to an increasing value of wall temperature and thermal conjugate parameter, the fluid temperature increased. As wall concentration increases, the fluid concentration also increased. Meanwhile, the velocity increasing as mixed convection and thermal conjugate parameter increased. Contradict, the velocity decreasing as the value of buoyancy ratio and frequency increased.

In current study, analysis is presented for peristaltic motion of applied magnetic field and entropy generation within couple stress (Cu/H2O) nanofluid through an endoscope. An endoscope contains two coaxial cylindrical tubes in which the internal tube is nonflexible while the external tube has sinusoidal wave passing through the boundary. Influences of mixed convection along with applied magnetic field are encountered as well. Formulated governing model is fabricated introducing long wavelength and creeping Stokesian flow approximation which are then analyzed numerically by utilizing Adams Bashforth method. For a physical insight, results are demonstrated to examine the behaviors of flow profiles and entropy generation number for emerging flow parameters with the help of graphs, bar-charts and tables.
