An improved time – dependent Hartree – Fock approach for scalar φ 4 QFT

The λφ 4 model in a finite volume is studied within a non–gaussian Hartree– Fock approximation (tdHF) both at equilibrium and out of equilibrium, with particular attention to the structure of the ground state and of certain dy-namical features in the broken symmetry phase. The mean–field coupled time–dependent Schroedinger equations for the modes of the scalar field are derived and the suitable...

Cooling Performance Analysis of Water-Cooled Heat Sinks with Circular and Rectangular Minichannels Using Finite Volume Method

In this paper, the cooling performance of water-cooled heat sinks for heat dissipation from electronic components is investigated numerically. Computational Fluid Dynamics (CFD) simulations are carried out to study the rectangular and circular cross-sectional shaped heat sinks. The sectional geometry of channels affects the flow and heat transfer characteristics of minichannel heat sinks. T...

Equilibrium condition nonlinear modeling of a cracked concrete beam using a 2D Galerkin finite volume solver

A constitutive model based on two–dimensional unstructured Galerkin finite volume method (GFVM) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. The developed iterative solver treats concrete as an orthotropic nonlinear material and considers the softening and hardening behavior of concrete under compression and tension by using...
