Presentation

Abstract

The strand grid approach is a flow solution method where a prismatic-like grid using "strands" is grown to a short distance from the body surface to capture the viscous boundary layer and the rest of the domain is covered using an adaptive Cartesian grid. The approach offers several advantages in terms of nearly automatic grid generation as well as the ability to implement fast and efficient flow solvers. This talk will provide an overview of a recently developed multi-strand solver called mStrand, which will be part of the Army's high-fidelity CFD/CSD rotorcraft simulation framework - Helios. The talk will show detailed validation of the solver on problems with varying degree of complexity.

Biography

He received his Ph.D. in Aerospace Engineering from the University of Maryland in 2009. After his Ph.D., Lakshminarayan has two postdoc experiences, one at the University of Maryland and the other at Stanford University.

Seminar Participation

Attending In Person

For select seminars, you may wish to attend in-person if you are in the vicinity of NASA Ames Research Center. These AMS seminars are held in Building N258 in Room 127, just off the front lobby. Sessions available to attend in-person will be indicated in the announcement information. In-person participants without NASA badges will need a valid visitor badge (US citizenship or permanent residency is required) to enter the facility.
