Journal ArticleDOI
TL;DR: In this paper, numerical analysis of incompressible viscoelastic fluid flow is discussed using mixed finite element Galerkin method, which is assumed as the constitutive equation, stress components could not be eliminated from the governing equation system.

Journal ArticleDOI
TL;DR: In this article, a general finite difference formulation is presented for deriving an accurate and stable finite-difference scheme, which introduces a new concept of "decay function" which is determined analytically at each grid point.

Journal ArticleDOI
TL;DR: In this paper, the flow in the entrance region of long ducts of rectangular and polar cross sections is studied using the three-dimensional parabolized Navier-Stokes equations, together with the energy equation, for an incompressible viscous fluid.

Journal ArticleDOI
TL;DR: In this article, the authors considered Laminar incompressible flow in rectangular channels and derived a two stream function, velocity, vorticity system, independent of the Reynolds Number, with a combined iterative ADI/point-relaxation numerical procedure.

Journal ArticleDOI
TL;DR: In this paper, the influence of boundary and initial conditions on time-dependent finite-difference solutions of quasi-one-dimensional duct flows was studied and it was shown that subsonic solutions require pressure, temperature and velocity to be fixed at both the duct inlet and exit.

Journal ArticleDOI
TL;DR: In this paper, a wall element is introduced to avoid using elements with extremely large aspect ratios and to attempt a better representation of near wall changes in velocity, and the applicability of the method is illustrated by comparing with published experimental and numerical data.

Journal ArticleDOI
TL;DR: The axisymmetric flow of a swirling viscous, incompressible fluid jet inside confining cylindrical boundaries has been numerically investigated using the well-known implicit finite-difference scheme as discussed by the authors.

Journal ArticleDOI
TL;DR: In this article, a numerical technique is developed to predict the two-dimensional transient natural convection heat transfer within a horizontal cylinder, which is a modification of an alternating-direction implicit (ADI) scheme wherein the convective terms are evaluated explicitly.

Journal ArticleDOI
TL;DR: In this article, a numerical analysis of periodic tidal flow is presented, based on the mixed approach of the finite element method and the perturbation method by postulating periodic motion.

Journal ArticleDOI
TL;DR: In this paper, the applicability of polynomial spline interpolation and Hermitian collocation has been evaluated for simulating the thicker, higher-shear turbulent boundary layer on a flat plate, with and without mass transfer.

Journal ArticleDOI
TL;DR: In this paper, a computational scheme based on the singularities distribution was developed to treat the transonic potential plane flow, and the singularity distribution was used to solve the problem.

Journal ArticleDOI
TL;DR: An optimization procedure is used based on one-dimensional analysis of the turbine performance that includes loss predictions due to passage losses, disk friction and clearances.

Journal ArticleDOI
TL;DR: In this paper, an integral procedure using spline polynomials is described for the two-dimensional boundary layer equations, where each term in the equations, rather than each independent variable, is approximated with a spline curve fit.


Journal ArticleDOI
TL;DR: In this article, the authors analyzed the flow field, temperature field and heat transfer rates in cylindrical shrouded cavities with rotation, recirculation and coolant through-flow.

Journal ArticleDOI
TL;DR: In this article, a modified version of the local stability scheme is proposed for practical application, which preserves the stability character at each point in the flow region and switches over to the van Leer scheme near shocks only.

Journal ArticleDOI
TL;DR: In this paper, a desk analogue computer was used to draw normalized curves for positive and negative particle concentrations (n +,n − ) and potential (y) vs the distance from a spherical probe surface for a slightly ionized continuum plasma.

Journal ArticleDOI
TL;DR: In this article, the laminar steady flow of air through moving narrow deep circumferential grooves on a rotor is studied and three dimensional developing velocity profiles and pressure distributions are presented for a variety of operating conditions.

Journal ArticleDOI
TL;DR: In this article, the modified local stability scheme is applied to several two-dimensional problems (blunt body flow, regular reflection of a shock and lambda shock) and is shown to be better than that achieved by the other first-order schemes and almost identical to the second order schemes incorporating artificial viscosity.
