BEHAVIOR OF NON-NEWTONIAN FLUID IN A LID-DRIVEN CHAMBER WITH HEATED BODIES SUBJECTED TO A UNIFORM MAGNETIC FIELD
Recent studies have attempted to find methods and techniques that enable the development of heat transfer within thermal transformers. For this purpose, this paper includes a numerical simulation of a non-Newtonian fluid inside a chamber with four hot bodies. The chamber is exposed to a magnetic field of constant and uniform intensity. Also, the up...

NUMERICAL SIMULATIONS OF BLOOD FLOW THROUGH LEFT VENTRICLE USING SPH AND FVM METHODS – A COMPARATIVE STUDY
This paper presents a comparative analysis of numerical simulations of blood flow through the left ventricle using SPH (LS-DYNA) and FVM (Ansys Fluent) solvers. Numerical simulations based on SPH and FVM methods can provide a more comprehensive understanding of cardiac blood flow patterns. In Fluent, left ventricle walls were modeled as boundary co...

NUMERICAL ANALYSIS OF COMPOUND PARABOLIC SOLAR COLLECTOR WITH TWO GLASS COVERS
In a compound parabolic solar collector, a glass cover is normally used for decreasing the rate of heat loss from the absorber. In this paper, a solar collector with two glass covers and a concentration ratio of 1.6 is simulated and examined for the purpose of higher performance. The distance between covers is 45 mm and the cavity of solar collecto...

CLOSED-FORM SOLUTION OF A METAL PLATE WITH A CENTRAL CRACK UNDER TENSION
Accurate prediction of stress and displacement in plates with central cracks is vital for engineering design safety. However, the impact of finite plate size on stress and displacement distribution is an important factor that has not been fully addressed in previous studies, highlighting the need for further investigation. Thus, this study presents...

THE EFFECT OF THERMOPHYSICAL PROPERTIES ON NONLINEAR THERMAL-SOLUTAL CONVECTIVE FLOW OF CASSON NANOFLUID OVER AN INCLINED SURFACE WITH HIGHER ORDER CHEMICAL REACTION
The combined effect of Soret-Dufour, higher-order chemical reaction and variable thermophysical properties on nonlinear thermal and solutal convective flow of a non-Newtonian fluid (Casson nanofluid) over a slanted surface is analyzed. The nonlinear dimensionless equations governing the fluid flow are transformed into ordinary differential equation...

THERMAL ANALYSIS OF LAMINAR WATER FLOW OVER A BACKWARD FACING CHANNEL WITH CARBON NANOPARTICLES
In the last few years, the thermo-hydraulic simulation of nanofluid flow bifurcation phenomena has become of great interest to researchers and a useful tool in many engineering applications. FVM has been employed in this article to numerically explore the laminar water flow over a backward facing channel with or without carbon nanoparticles (CN). T...

FLEXURAL ANALYSIS OF THERMALLY LOADED SYMMETRIC SANDWICH BEAM
In the present paper, an attempt has been made to study the effect of temperature gradient on simply supported symmetric sandwich beam. A Navier’s solution technique is used. The temperature profile is assumed to be linear across the thickness of a sandwich beam. A higher order beam theory (HBT) is used to include the effect of s...

EFFECT OF VERTICAL POSITION OF HEATED SQUARE OBSTACLE ON NATURAL CONVECTION IN POROUS CAVITIES SATURATED BY A NANOFLUID USING BUONGIORNO'S TWO PHASE MODEL
Laminar flow, heat transfer and mass transfer of nanofluid in a porous medium have been studied using Buongiorno’s two phase model. The porous medium in place is a non-uniform octagonal shape. In order to increase the rate of heat transfer within the porous cavity, it has been equipped with a heated square at different vertical p...

ON THE EQUILIBRIUM OF STRATIFIED VISCOELASTIC PLASMA WITH QUANTUM PRESSURE AND SUSPENDED PARTICLES SATURATING POROUS MEDIUM
Stability of stratified incompressible viscoelastic plasma arranged in horizontal strata with quantum pressure and dust particles saturated by a porous medium is investigated. The rheology of the plasma is described by the Walters (model B). The set of non-linear partial differential equations defining the physical system are reduced to linear ordi...
