ABSTRACT: The marine atmospheric boundary layer influences the evolution of evaporation duct height (EDH) by altering the vertical profile of the refractive index. The EDH is a crucial parameter for marine and naval communication. Many studies have demonstrated the sensitivity of boundary layer similarity theory in estimating the vertical profile of refractive index. The current study modifies …
ABSTRACT: The morning transition is the period when the planetary boundary layer (PBL) transitions from stable to unstable conditions. It is critical that numerical weather prediction (NWP) models sufficiently represent the various forcings that contribute to the PBL heat and moisture budgets during the morning transition, as they impact forecasts of air quality, turbulence, aerosol dispersion,…

Boundary-Layer Theory", 9th edition, written by Hermann Schlichting and revised by Klaus Gersten, is a nearly legendary textbook that provides a comprehensive overview of boundary-layer theory and its applications across all areas of fluid mechanics, with a particular emphasis on flow over bodies (e.g., aircraft aerodynamics). This latest edition features an updated reference list and over 100 …
Spanning the entire range of viscous fluid flows of engineering interest - from low-speed to hypersonic flows - this volume introduces and analyzes turbulent flows, the physics of turbulent shear flows, and turbulence models. It covers older analytical methods which are widely used in preliminary design, especially for design optimization studies, and offers concurrent treatment of momentum, he…
Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the fi…
