Comparison of the Triple-Deck Theory, Interactive Boundary Layer Method, and Navier-Stokes Computation for Marginal Separation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The steady two-dimensional marginal separation of an incompressible boundary layer flow within a channel was solved independently by three different methods: the triple-deck method of marginal ...
Numerical and Experimental Study of the Interaction of a Spark-Generated Bubble and a Vertical Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An understanding of the fundamental mechanisms involved in the interaction between bubbles and structures is of importance for many applications involving cavitation erosion. Generally, the final ...
Numerical Computation of Tip Vortex Flow Generated by a Marine Propeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The uniform flow past a rotating marine propeller was studied using incompressible Reynolds-averaged Navier-Stokes computations with the Baldwin-Barth turbulence model. Extensive comparison with the ...
Study of Tip Vortex Cavitation Inception Using Navier-Stokes Computation and Bubble Dynamics Model
