An inquiry into atmospheric escape driven by photoionization. We begin with a brief survey of the relevant historical development of atmospheric escape, spanning from the origins of kinetic theory to the age of exoplanets. Collisional mechanisms justifying the continuum assumpti…

This study is concerned with the numerical analysis, formulation, programming and computation of solution of steady, 3D conservation equations of reacting laminar duct flow heat and mass transfer in ducts of arbitrary cross-sections. The non-orthogonal boundary-fitted coordinate…
Bottom of the mountainous rivers is generally composed of natural gravels. Flow depth in such rivers is generally shallow, with the ratio of water depth to size of bed materials (known as relative submergence) rarely higher than 20. In this type of flow, gravels intrusion induce…
The focus of the research is the evaluation of dynamic and static pressures acting on floating bodies. Specifically, these pressures result from large motions of a multi-hull ship in 6 dof. The components of the dynamic pressure are radiation, diffraction, and the Froude-Kriloff…
The viscosity of the QGP is a presently hotly debated subject. Since its computation from first principles is difficult, it is desirable to try to extract it from experimental data. Viscous hydrodynamics provides a tool that can attack this problem and which may work in regions …
The Wax Lake Delta (WLD) is located at the downstream end of the Wax Lake outlet, approximately 13 miles upstream from Morgan City, Louisiana. In 1942 the United States Army Corps of Engineer (USACE) dredged Wax Lake Outlet channel from the lower Atchafalaya River to reduce floo…
Indian River Inlet (IRI), DE, USA, is located at roughly the midpoint of ~ 40 km Atlantic coast of Delaware and is the major waterway that connects the Atlantic Ocean to two Delaware inland bays. Twin jetties constructed in late 1930s to keep the inlet from filling also interrup…
The full Navier-Stokes equations were employed with a single-fluid model and a front tracking scheme to study large cylindrical, spherical, and ellipsoidal bubbles in a free shear layer. This approach allows direct simulation of the multiphase flow by wholly incorporating the bu…
