Analysis of a Steady MHD Mixed Convection Fluid Flow in a Microchannel within Permeable Walls with Suction and Injection Parameters

Glory Oyintombra Weinor, Kolawole Emmanuel Adesina, Godwin Micah Smart, Emmanuel Kofi Asuako Wie-Addo, Wisdom Benson
This research work focuses on the analysis of a steady fluid of a convection mixed flow within a permeable channel under the influence of suction and injection parameters. The fluid is presumed to be incompressible, and an existing model was used to formulate the governing equations with appropriate boundary conditions. The governing equations directing the flow system are modeled, non-dimensionalized, and transformed into ordinary differential equations where appropriate methods were used to so...

Effect of Porosity on the Laminar Condensation Type Thin Film on a Vertical Wall in Forced Convection

Momath Ndiaye, Madialène Sène, Goumbo Ndiaye, Mamadou Salif. Mané
Studies concerning induced heat transfer by the condensation in forced convection of a thin film of a saturated vapor in medium porous, have received particular attention because of their numerous applications in various fields of technology. Thus, the presence of a layer of porous material on a plane wall generates an increase in heat transfer compared with that observed for a flat plate, subject to the same aeraulic and thermal conditions. This prompted us, given the large field of application...

Analysis of Chemically Reactive Hydromagnetic Maxwell Fluid Conveying Tiny Particles Due to Navier Partial Slip

Olubode Kolade Koriko, Victor Ayodeji Oladipupo, Adeola John Omowaye, Sunday Tunbosun Oni
The analysis of nanofluids in the solar thermal system is very fascinating owing to its important engineering applications (i.e., solar collectors). Aside from these the non-Newtonian boundary layer fluid flow has experienced considerable attention due to uprising engineering applications in the solar thermal field. This work investigates the analysis of chemically reactive hydromagnetic Maxwell fluid conveying tiny particles due to Navier partial slip. The governing equations that model the tra...

Modeling a Geothermal Field: A Not-Trivial Starter Kit

Luca Meacci
In this paper, we discuss the assumptions, the balances, and the constitutive relationships in order to provide a set of tools for the mathematical modeling of a geothermal system. In particular, we present a model for pressure and saturation supposing that: 1) the geothermal fluid flows in a porous medium, 2) it is composed of pure water, 3) the simultaneous presence of the gaseous (vapor) and liquid phases occurs, and 4) the effects of capillarity action can be introduced.

Pressure Control of High Pressure Tubing

Shilin Hu, Yu Quan
This article focuses on how to control the pressure in the high-pressure tubing. First, an overall analysis of the system is performed to determine the pressure balance conditions of the high-pressure fuel pipe; that is, the mass of fuel flowing out of the high-pressure fuel pipe is equal to the mass of fuel flowing in. This article uses Excel to fit and organize the data in all data processing. When solving differential equations of pressure and density, the fourth-order Runge-Kutta formula is ...

Pressure Variation in a Fluid Flow over Non-Uniform, Porous Bottom Topography

Godwin Christopher Ezike Mbah, Emmanuel Oluwakorede Oshilim
This paper presents pressure variation in fluid flow over a porous media. In the model, we considered water as an incompressible fluid: the flow as nonsteady and uniform. We derived an equation for the nonuniform bottom topography (flow depth) and substituted into the governing equation for shallow water flow with nonuniform bottom topography. We made use of Darcy’s law to construct equation for Darcy flux, which in turn related pressure gradient to the flow ve

Comparison of Mathematical Methods to Obtain Concentration and Temperature of Newtonian Fluids in Tubular Reactors

Diego Alves de Miranda, Renato Cristofolini, Emerson José Corazza, Gilson Joao dos Santos, Claiton Emilio do Amaral
In several areas of engineering, it is possible to put real problems in mathematical functions; when we represent a problem with variables in the form of function, we were able to extract various information from it. This paper compared two different mathematical methods, being the finite difference method and the Fourth Order Range-Kutta method, to analyze the concentration and temperature of
