Water impact phenomenon of general bow section is a critical event for planning hulls. In this paper, the water entry of several arbitrary bow sections is investigated. For this purpose, arbitrary bow shapes which are introduced by Lewis form approximation are considered. In order to obtain pressure distribution and free surface profile, volume of fluid (VOF) method coupled with finite volume m...

This paper studies the three dimensional (3D) simulation of fluid flows through the ball grid array (BGA) to replicate the real underfill encapsulation process. The effect of different solder bump arrangements of BGA on the flow front, pressure and velocity of the fluid is investigated. The flow front, pressure and velocity for different time intervals are determined and analyzed for potential ...

This paper focuses on the thermal modelling of power transformers using physics-informed neural networks (PINNs). PINNs are trained to consider physical laws provided by general nonlinear partial differential equations (PDEs). The PDE considered for study transformer’s behaviour is heat diffusion equation with boundary conditions given ambient temperature at bottom and top-oil top. model one di...

This paper summarizes one-dimensional using finite difference method (FDM), of characteristics (MOC), especially more volume (FVM). The discussion is briefly extended two-dimensional modelling, as well computational fluid dynamics (CFD) approaches. Finite methods particular note, si...

With the increased use of “Virtual Machines” (VMs) as vehicles that isolate applications running on the same host, it is necessary to devise techniques that enable multiple VMs to share underlying resources both fairly and efficiently. To that end, one common approach is to deploy complex resource management techniques in the hosting infrastructure. Alternately, in this paper, we advocate the u...

Abstract This work presents a comparison of two-dimensional numerical solutions unsteady free surface flow. is simulation the dam-break wave with different configurations using based-mesh finite volume method and meshless smoothed particle hydrodynamics (SPH). Two well-known approaches, widely used in computational fluid dynamics (CFD). These techniques have proven their robustness treatment su...

This paper focuses on using the numerical finite volume method (FVM) and artificial neural network (ANN) in order to propose a correlation for computing the entrance length of laminar magnetohydrodynamics (MHD) channels flow. In the first step, for different values of the Reynolds (Re) and Hartmann (Ha) numbers (600<ReL increases.

Variabilities in polyamide 6 (PA6) composite manufacturing by liquid processes can occur due to polymerization, crystallization, and flow through a fibrous preform. Numerical simulations of the process predicting kinetics facilitate optimization. This study proposes an efficient modeling approach that be integrated current simulation discretization methods such as finite volume method (FVM) whi...
