Computed Transient Supercavitating Flow over a Projectile

To improve the understanding of the unsteady behavior of supercavitating flows, the author used a three-dimensional Navier-Stokes code (CFDRC, 2000) to model the two-phase flow field around a hemisphere cylinder. The governing equations are discretized on a structured grid using an upwind difference scheme. For different body shapes and cavitation numbers, the cavity shape was determined over t...

A Simple Approach to Estimating Three-Dimensional Supercavitating Flow Fields

A simple method is formulated for predicting three-dimensional supercavitating flow behind cavitators subject to gravitational acceleration and motion of the cavitator. The method applies slenderbody theory in the context of matched asymptotic expansions to pose an inner problem for the cavity evolution downstream from the locus of cavity detachment. This inner problem is solved by means of a c...

For over three decades the graph isomorphism problem has tantalized researchers in algorithms and complexity. The study of this problem has stimulated a lot of research and has led to the discovery of important concepts in the area. In this article we take a fresh look at isomorphism problems and highlight some open questions.

Basic Beliefs of Graceful Forgiveness on the Basis of the Analysis of Verses 85 and 86 of Chapter Al-Hijr

Man's moral behavior is always influenced by his beliefs and faiths. Although moral philosophers do not have consensus about the extent of this effect, the least that can be said is that beliefs are ground-preparing. Accordingly, the Holy Koran, in its moral precepts, has taken into account the beliefs associated with them, and in this way has provided the psychological grounds for carrying out...
