Turbulent Boundary Layer Height Scales in Hurricanes
Kishore Ram Sathia, Marco Giovanni Giometto
Boundary layer processes drive the air-sea exchange of momentum, heat, and moisture that powers and shapes hurricanes. The height of the boundary layer is a critical parameter in e…
On the structure and dynamics of secondary flows over multi-column roughness in channel flow
A. S. Sathe, W. Anderson, M. Calaf +1
Secondary flows induced by spanwise heterogeneous surface roughness play a crucial role in determining engineering-relevant metrics such as surface drag, convective heat transfer,…
An analytical solution for horizontal velocity profiles in the hurricane boundary layer
Kishore R. Sathia, Marco G. Giometto
Theoretical analyses of the hurricane boundary layer have traditionally relied on slab models, which provide a limited description of wind profiles. Literature on height-resolving…
Surrogate Modeling of Urban Boundary-Layer Flow
Gurpreet S. Hora, Marco G. Giometto
Surrogate modeling is a viable solution for applications involving repetitive evaluations of expensive computational fluid dynamics models, such as uncertainty quantification and i…
The Structure of Turbulence in Pulsatile Flow over Urban Canopies
Weiyi Li, Marco G. Giometto
The transport of energy, mass, and momentum in the atmospheric boundary layer (ABL) is regulated by coherent structures. Although past studies have primarily focused on stationary…
