This work describes a simple thermodynamic model of the hydrogen gas at low densities and for temperatures going from those involving quantum rotations of ortho- and para-hydrogen up to the fully ionized state. The closed-form energy levels of Morse

A subgrid stabilization technique is developed for solving the two-dimensional incompressible Navier–Stokes equations at high Reynolds numbers. The time marching algorithm is based on a well-established fractional-step pressure-correction projectio

The paper's focus is the calculation of unsteady incompressible 2D flows past airfoils. In the framework of the primitive variable Navier–Stokes equations, the initial and boundary conditions must be assigned so as to be compatible, to assure the c

In this work, we consider the three-dimensional vector Poisson-like equation supplemented by a nonstandard set of three scalar boundary conditions consisting of the simultaneous specification of the divergence of the unknown, its normal component, an

This article provides accurate spectral solutions of the driven cavity problem, calculated in the vorticity-stream function representation without smoothing the corner singularities--a prima facie impossible task. As in a recent benchmark spectral ca

This paper describes a variational formulation for solving the time-dependent Navier–Stokes equations expressed in terms of the stream function and vorticity around multiple airfoils. This approach is an extension to the case of multiply connected

This paper provides comparisons between experimental data and numerical results for impulsively started flows in a three-dimensional rectangular lid-driven cavity of aspect ratio 1:1:2 at Reynolds number 1000. The initial evolution of this flow is st

In this contribution, a fully spectral projection method for simulating the flow over a flat plate is presented. The incompressible Navier–Stokes equations are integrated in time using a second order fractional step method, while suitable Legendre

In this review the conditions to be imposed on the vorticity in the calculation of two-dimensional incompressible viscous flows are discussed. Existing boundary vorticity formulas, commonly regarded as a surrogate Dirichlet boundary condition for the

This paper provides an analysis of a fractional-step projection method to compute incompressible viscous flows by means of finite element approximations. The analysis is based on the idea that the appropriate functional setting for projection methods
