Microfluidics is a multidisciplinary area founding applications in several fields such as the aerospace industry. Microelectromechanical systems (MEMS) are mainly adopted for flow control, micropower generation and for life support and environmental control for space applications. Microflows are modeled relying on both a continuum and molecular approach. In this paper, the compressible Navier–S...

INTRODUCTION About 30 percent of the worldwide death is due to cardiovascular diseases. Clinical simulation is a promising filed that can help to understand diseases, their nature and intervention's effects. The simulated models are flexible and make it easy to study the changes' effects and help to select the appropriate interventions. This narrative review aims to report common methods for th...

A three-dimensional multi-scale discrete–continuum model (Finite Volume Method × Discrete Element Method, FVM DEM) is developed for a discrete-based description of the mechanical behavior granular soils in boundary value problems (BVPs). In such scheme, constitutive response material derived through direct DEM computations on representative volume element attached to each mesh element. The appr...

One of the most efficient methods of reducing drag on planing craft is the use of transverse step on the bottom of a hull. Applying steps on the hull reduces the contact area with water and as a result, it reduces drag of the craft. Planing craft are able to have one or two transverse steps. In this paper, numerical hydrodynamic performance of the stepped planing craft and its step height effec...

The atmospheric flow and dispersion of traffic exhaust were numerically studied in this work while considering a model street canyon intersection city. finite volume method (FVM)-based large-eddy simulation (LES) technique line with ANSYS Fluent have been used for pollutant modelling through the consideration boundary layer (ABL). Hexahedral elements are considered computational domain discreti...
