Full potential solution of transonic quasi-3-D flow through a cascade using artificial compressability [PDF]

open access: yes
The three-dimensional flow in a turbomachinery blade row was approximated by correcting for streamtube convergence and radius change in the throughflow direction.

The design and performance estimates for the propulsion module for the booster of a TSTO vehicle [PDF]

open access: yes
A NASA study of the propulsion systems for possible low-risk replacements for the Space Shuttle is presented. Results of preliminary studies to define the USAF two-stage-to-orbit (TSTO) concept to deliver 10,000 pounds to low polar orbit are described ...

Towards the Evolution of Novel Vertical-Axis Wind Turbines

open access: yes, 2012
Renewable and sustainable energy is one of the most important challenges currently facing mankind. Wind has made an increasing contribution to the world's energy supply mix, but still remains a long way from reaching its full potential. In this paper, we

Fluid machines: Expanding the limits, past and future [PDF]

open access: yes
During the 40 yr period from 1940 to 1980, the capabilities and operating limits of fluid machines were greatly extended. This was due to a research program, carried out to meet the needs of aerospace programs. Some of the events are reviewed.

Transonic Flow of Wet Steam — Numerical Simulation

open access: yesActa Polytechnica, 2012
The paper presents a numerical simulation of the transonic flow of steam with a non-equilibrium phase change. The flow of steam is approximated by a mixture model complemented by transport equations for moments. Proper formulation of the problem consists

Recent progress in inverse methods in France [PDF]

open access: yes
Given the current level of jet engine performance, improvement of the various turbomachinery components requires the use of advanced methods in aerodynamics, heat transfer, and aeromechanics.
