This book was released on 1964 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The equations governing the hypersonic flow about a magnetized body are solved numerically. The solutions obtained illustrate the effects of Reynolds number and magnetic parameter on the structure of the applied magnetic field. The results show that, for magnetic parameters larger than a critical value, numerical solutions do not exist. A critical magnetic parameter is considered to result from an assumption of a given magnetic field at the shock. By increasing the conductivity, and thereby the induced magnetic field, the applied field at the shock disappears. This in turn violates the basic assumption of a finite field at the shock. It is concluded that the applied magnetic field can be defined only at the body where it is a natural characteristic of the problem. (Author).

This book was released on 1965 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation is presented of the hypersonic viscous and inviscid flow past a spherical body which contains a magnetic dipole field aligned with the flow. Local-similarity solutions of the flow field are assumed near the stagnation point. The solution found differs from previous solutions in that the magnetic field is defined on the body rather than at the shock. The numerical results indicate that the critical values of the magnetic interaction parameter no longer appear as in previous works and that the shock displacement is much larger than formerly found for magnetic interaction parameters less than one. The latter result suggests that a magnetic field is a more useful device for controlling the hypersonic flow about a body than previously thought. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic body forces are nonconservative. The effects of such forces are studied here in the case of inviscid incompressible flow about a blunt body. The nonlinear simultaneous partial differential equations describing the flow can be solved in various regimes corresponding to certain values of two parameters: RM, the magnetic Reynolds number, and A where A to the -1/2 power is the Alfven number. For the case of small Rm, and small magnetic force coefficient, S, equations can be derived which are linear and independent. These are solved for some particular unsteady flows, and the results show that, in these cases, vorticity is introduced in such a way that it is independent of time. The equations are linearized by using the velocity field of ordinary hydrodynamics (OHD) in the convective derivatives. This technique is valid for all Rm provided either A or S is small. For large Rm, it results in a solution showing a boundary-layer character. Two results are of interest: First, the appearance of the downstream non-diffusive trail of vorticity in the small Rm, small S case; Secondly, the fact that for all cases studied the region of significant current density is close to the body, and any wake-like effect is either highly diffusive (small Rm) or extremely weak (large Rm).

Download or read book Hypersonic Viscous Flow Near the Stagnation Streamline of a Blunt Body I a Test of Local Similarity written by Hsiao C. Kao and published by . This book was released on 1964 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flow near the stagnation streamline of a blunt body is often analyzed by using the approximation of local similarity, which reduces the equations of motion to a system of ordinary differential equations. This scheme is equivalent to truncating at one term a powerseries expansion of the flow variables from the stagnation point, neglecting backward influence. The accuracy of such a truncation is examined. The principal assumption is that the Navier-Stokes equations are valid. In addition, it is assumed that the validity of the first truncation can be evaluated by comparing it with the second. The conclusion is that the usual assumption of local similarity is remarkably accurate for predicting flow quantities near the stagnation streamline. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A simplified form of the Navier-Stokes equations was used to describe the flow in the shock layer of a blunt body. The equations are solved near the axis of the body by using the method of series truncation. The main method of solution is a finite difference method, which in principle allows one to handle axisymmetric bodies of arbitrary shape. The body shape is assumed to be given and the bow shock shape is determined step by step. (Author).
