Opis:: A study of a suddenly accelerated plate with variable approximated electronegativity with MHD fluid provoked by chemical reaction and radiation is made. The governing hydrodynamical equations of the physical problem was formulated and its solution and analysis showed that increase in electroconductivity, prandtl number, Reynold’s number, Grashof number, chemical reaction and radiation all result to a corresponding increase in the velocity profile of the fluid while magnetic field increase results to a decrease in the velocity profile of the fluid. The shear stress at the wall of the plate was also determined.

Opis:: A study on the comparison of the pressure-driven Poiseuille flow and acceleration-driven Poiseuille flow was made by analyzing the resulting models of the flow configuration. It is shown that at the hydrodynamic level, there exist a difference in magnitude of the two flows but at the microscopic level the body force and the pressure gradient which are the driving forces are different due to spatial variations in the both flows.

Tytuł:: Characteristics of thermal explosions on Newtonian and non-Newtonian fluids
Autorzy:: Ngiangia, Alalibo T.
Powiązania:: https://bibliotekanauki.pl/articles/1191471.pdf
Data publikacji:: 2016
Wydawca:: Przedsiębiorstwo Wydawnictw Naukowych Darwin / Scientific Publishing House DARWIN
Tematy:: Newtonian fluids
non-Newtonian fluid
Thermal explosions’ Frank-Kamenestkii parameter
Semenov parameter
Opis:: An analytical study of thermal explosion on Newtonian and non-Newtonian fluid is carried out. Approximate solutions to the governing equations and analysis of the study in the Newtonian case, showed that an increase in Frank-Kamenestkii parameter and that of the Semenov parameter decreases the minimum temperature of the reacting fluid thereby delaying the initiation of thermal explosions while additional heat source brings about early initiation of thermal explosions. The same observation was deduced in the non-Newtonian case but in varying degrees.

Tematy:: MHD
Electrconductivity

Couette flow
Opis:: A study of Couette flow in cylindrical coordinate under the influence electroconductivity and magnetic field was carried out. Approximate solution of the governing equations and its analysis show decrease in temperature as a result of increase in radiation and Prandtl number. The study also reveals that increase in grashof number, Reynolds number, Prandtl number and electroconductivity result in an increase in velocity distribution while magnetic field increase, lead to a decrease in velocity. The shear stresses of the outer and inner cylinders at the wall of the plates and the heat flux is also determined.
