Chemical reactions occur everywhere in our everyday life, for example, in the human body, in cell phone batteries, in a rocket engine and in the pharmaceutical and chemical industry. In this research the model provides a study of an elementary, exothermic, 2nd-order reversible reaction in a tubular reactor (liquid phase, laminar flow regime). The aim of this project is to study numerically the effect of convective Heat and Mass transfer flow of a viscous fluid in the reactor. Assuming that the variations in angular direction around the central axis are negligible makes it possible to reduce the model to a 2D axisymmetric model. The investigation of forced convection flow, heat and mass transfer phenomena through a tubular reactor is carried. The implications of Reynolds number (Re) and Prandtl number (Pr) on the flow structure, heat transfer and mass transfer characteristics are presented. The results are presented in the form of stream functions, isothermal lines, iso-concentrations, surface temperature, arrow plot, average Nusselt number and Sherwood number, mean temperature, average concentration and mean velocity.

This study investigated the effects of the aspect ratio of the cavity for average fluid temperature at exit port, average Nusselt number, maximum temperature of the fluid in the domain, drag coefficient, isotherms and streamlines on behalf of different Hartmann numbers and Rayleigh numbers. Solution of governing equations of momentum and energy has been made by finite element technique. Above mentioned parameters such as an aspect ratio which is cavity height to cavity length change from Ar = 0.5 to 2 for different Rayleigh numbers and Hartmann numbers which change from Ra = 10 3 to 10 5 and Ha = 0 to 50 respectively. Prandtl number Pr = 7 and Reynolds number Re = 100 is fixed in this simulation. It is found that variation of the aspect ratio makes an important effect for higher values of Rayleigh numbers. Heat transfer enhances with increasing of aspect ratio. Increasing of Hartmann number decreases the heat transfer inside the cavity.

“…Later, Alimi et al [21] studied the buoyancy effects on mixed convection heat and mass transfer in an inclined duct preceded with a double step expansion. Brown and Lai [22] numerically examined combined heat and mass transfer from a horizontal channel with an open cavity heated from below. Since heat and contaminant sources usually co-exist indoors, the present work is to numerically study the double-diffusive mixed convection in a vented cavity due to the discrete heat and contaminant sources.…”

A numerical study has been carried out for laminar double-diffusive mixed convection in a twodimensional vented square cavity with discrete heat and contaminant sources applied on the bottom wall. An external air flow enters the cavity through an opening located at the bottom of the left vertical wall and exits from an opening located at the three different positions of the opposite wall. The developed mathematical model is governed by the two-dimensional continuity, momentum, energy, and concentration equations. The governing equations, written in non-dimensional form are solved by using Galerkin finite element method with triangular grid discretization system. The Reynolds number is fixed at 100 and the working fluid is considered as air. Numerical simulations are carried out for different combinations of the thermal Grashof numbers and results are presented in terms of streamlines, temperature and concentration distributions. The results indicate that the average Nusselt and Sherwood numbers on the heat and contaminant sources strongly depend on the positioning of the exit opening.
