MAGNETOHYDRODYNAMICS AND POWER-LAW FLUIDS IN DOUBLE LID-DRIVEN CAVITY WITH SEMI-CIRCULAR BODIES
The use of complex fluids is one of the modern techniques used in small devices in order to enhance their thermal performance. This paper is a numerical study of a complex fluid imprisoned in a chamber with two hot bodies exposed to a magnetic field of constant intensity. The upper and lower walls move horizontally at a constant velocity, while the...

NUMERICAL ANALYSIS OF V-SHAPED PROTECTIVE PLATES AT VARIOUS ANGLES SUBJECTED TO BLAST LOADING – A COMPARATIVE ANALYSIS
The mechanical response of blast-resistant vehicles, such as Infantry Fighting Vehicles (IFVs), Mechanized Infantry Combat Vehicles (MICVs), Armored Personal Vehicles (APVs), and Mine-Resistant Ambush-Protected (MRAP) vehicles, is crucial for their effective design. When designing armored vehicles, it is important to achieve a balance between rigid...

PREDICTION OF DRAG AERODYNAMIC COEFFICIENT OF THE 155MM PROJECTILE UNDER AXISYMMETRIC FLOW USING DIFFERENT APPROACHES
The determination of the total aerodynamic load which negatively influences the movement of artillery projectiles is inevitable and indispensable in order to be able to increase or control their ranges. The main part of this aerodynamic load that has the most influence on projectile movement is the drag force, which acts in the opposite direction t...

NUMERICAL AND ANALYTICAL PREDICTION OF THE PROPAGATION OF DELAMINATION OF BONDED COMPOSITE REPAIR PLATES UNDER MECHANICAL LOADING
This study presents a numerical and analytical prediction of delamination of a repaired joint due to a defect in the composite under tensile loading. The three-dimensional finite element method is used to predict the delamination of a repaired plate with the VCCT method. The effects of the position of the delamination, percentage of the delaminated...

THE EFFECT OF ROTATION RATES, CYLINDER DIAMETER AND LATERAL BOUNDARIES ON STROUHAL NUMBER IN UNSTEADY REGIMES AT DIFFERENT REYNOLDS NUMBERS
The lateral boundary conditions, rotation rates parameters, domain size, cylinder diameter, and Reynolds number are all responsible for the variation of the Strouhal number. In this study, we have varied the domain size, lateral boundary conditions, downstream locations, and the cylinder diameter at specific values of Reynolds number for stationary...

FINITE ELEMENT ANALYSIS OF A KNEE JOINT DURING JUMP
Athletes experience high levels of stress during sports activities. One of the most common activities is jumping. This is a very complex activity, which can lead to injuries and long recovery periods. In this research, professional athletes performed jumps in order to obtain ground force values from a force plate. A combination of ground force meas...

UNSTEADY NUMERICAL INVESTIGATION OF FERROFLUID FORCED CONVECTION OVER A DOWNWARD STEP CONTAINING A ROTATING FINNED CYLINDER
The unsteady investigation of ferrofluid flow forced convection over a downward step containing a rotating finned cylinder is conducted numerically. The dimensionless partial differential equations of conservation equations for mass, momentum and energy and the boundary conditions associated with them are solved by using the finite element method. ...

COST-EFFECTIVENESS ANALYSIS OF IN SILICO CLINICAL TRIALS OF VASCULAR STENTS
Today, it takes ten to twelve years on average to complete a clinical trial before a new drug is approved and brought to marktet. Moreover, the evaluation of the efficacy and safety of drugs or devices has been performed in the linear and sequential manner with limited change over the past decade. The InSilc project is an EU funded project (www.ins...

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...
