On the structure and use of linearized block implicit schemes
W. R. Briley,Henry McDonald +1 more
TL;DR: It is demonstrated that the two-level version of the second and more recent “delta” form approximate factorization scheme of Warming and Beam and the earlier method of Briley and McDonald have identical linearized block implicit structures.
Journal ArticleDOI
Mixing Length and Kinematic Eddy Viscosity in a Compressible Boundary Layer
George Maise,Henry McDonald +1 more
TL;DR: In this article, the effect of Mach number on mixing lengths and kinematic eddy viscosities in the turbulent, flat-plate boundary layer has been evaluated using the generalized velocities suggested by Van Driest, using measured boundary-layer profiles, for a range of Reynolds numbers and Mach numbers from 0 to 5, on a single curve.
Patent
Multi-frequency jet ventilation technique and apparatus
TL;DR: In this article, inhaled gas pulses are generated by entraining humidified low pressure gas with pulses of high pressure entrainment gas, of variable frequency, duration and duty cycle, and are produced by modulating the flow of a highly pressured gas with a solenoid operated valve.
Journal ArticleDOI
Navier-Stokes analysis of solid propellant rocket motor internal flows
TL;DR: A multidimensional implicit Navier-Stokes analysis that uses numerical solution of the ensemble-averaged Navier Stokes equations in a nonorthogonal, body-fitted, cylindrical coordinate system has been applied to the simulation of the steady mean flow in solid propellant rocket motor chambers.
Journal ArticleDOI
Practical calculations of transitional boundary layers
Henry McDonald,R.W. Fish +1 more
TL;DR: In this article, a general finite difference procedure for computing the behavior of compressible two-dimensional boundary layers is presented together with a turbulence model which allows quantitative predictions of the location and extent of the transition region between laminar and turbulent flow as it is influenced by such disturbances as surface roughness and free-stream turbulence.
