This study examines mixed convection heat transfer in a lid-driven triangular cavity containing three heated horizontal finned cylinders immersed in power-law fluids. The cavity features inclined sidewalls maintained at a cold temperature, while the top adiabatic lid moves at a uniform velocity. The objective is to analyze the fluid’s behavio...

Micropumps are revolutionizing compact and autonomous monitoring systems due to their portability and efficiency. In this paper, we present a valveless piezoelectric micropump design. This micropump distributes gas and liquid using a PDMS membrane that moves in response to a force applied by a piezoelectric actuator. The proposed design aims to ach...

This paper aims at the development and implementation of an algorithm for the treatment of damage and fracture in smooth particle hydrodynamic (SPH) method, where free surface, crack opening, including its propagation and branching is modelled by weakening the interparticle interactions combined with the visibility criterion. The model is consisten...

The advancement of technology in the field of human health plays a significant and positive role, particularly in the realm of hearing. In this study, we propose a novel approach for middle ear prostheses. We constructed a finite element (FE) model of the ear with a pure titanium TORP prosthesis, which we validated using experimental results. Subse...

Over the last few decades, cardiovascular stents have emerged as crucial biomedical devices. Stents undergo cyclic physiological loading, which can lead to progressive accumulation of structural damage over time eventually resulting in a stent fracture. Considering the critical role of stents, it is necessary to assess their fatigue endurance and p...

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...

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...

This paper aims to predict the behavior of a complex fluid though a small-sized thermal exchanger. The fluid used is of shear-thickening type of power-law index (n = 1.4) and Prandtl number (Pr = 50). The Ostwald model was utilized to define the dynamic viscosity. The exchanger consists of three rectangular cross-section tubes placed inside a therm...
