Thermal and solutal performance analysis featuring fully developed chemically reacting micro-rotational convective flow in an open-ended vertical channel

Abstract

The effects of a baffle and chemical reaction (first-order) on liquid flow in an upright double-passage channel were studied using regular perturbation analysis. Each of the two streams has its pressure gradient, temperature and velocity, and the channel is partitioned into two channels by a thin baffle that is fully conductive and flat in shape. The coupled nonlinear ordinary differential equations are solved using appropriate boundary constraints. The analytical results are plotted for various important parameters and exhibited graphically relevant to the flow field at all baffles. Results reveal that the enhancement in the small perturbation parameter upsurges the temperature in both regions. The velocity, thermal and micro rotational fields increase with the increase in thermal and mass Grashof number. Here, an upsurge in Grashof numbers increases the buoyancy force, resulting in an upsurge in the velocity, temperature, and micro rotational fields. The micro rotational velocity falls in area I but increases in region II at various baffle positions as the ratio of Grashof number to Reynolds number rises. Results obtained for few more parameters such as material parameter suppress the flow because of microporous property and brinkman number which is considered as perturbation parameter it enhances the flow which is helps a lot for practical situations in engineering field. Analytical and numerical results hold good with each other in this work.
