The high noise levels generated by the jet exhaust from commercial and military aircraft make mixing-noise reduction an important objective. Crucial to this effort will be the availability of robust, rapidly computable noise models that can be used to guide and optimize noise control strategies.
We present a new method, which we call design-by-morphing, for the optimal design of the shape of an object.
Eddies, understood as regions of the flow, which maintain spatial and temporal coherence, are widely used by the turbulence community as a conceptual model to organize and understand the flow.
We use tools including Large-eddy-simulations, wind tunnel experiments and the framework provided by the Townsend attached eddy hypothesis to study the flow physics in high Reynolds number turbulent boundary layers.
Despite being ubiquitous in technical applications (gas turbines, diesel engines, rocket engines), supercritical injection is generally considered not well understood.
It is well recognized that computational science is the third pillar of discovery along with theory and experiments.
In the past couple of decades, computational fluid dynamics of multiphase flows has evolved tremendously.
It is critical to understand how wind turbine wakes interact with the atmospheric boundary layer (ABL) in order to better estimate the wake loss in a wind farm.
The transport of sediments due to turbulent wave, current, and tidal flows can have lasting social and environmental consequences.
