Molecular Dynamics Study of Fluid Solid Interfacial Slip and Its Effect on Aerodynamic Drag [PDF]
MATEC Web of Conferences, 2017 Interfacial hydrodynamic slippage is controlled by two factors say physical structure and chemical composition. Various studies have been conducted experimentally which try to connect the physical structure of the surface and its chemical property on the interfacial wettability.

Capturing the Knudsen layer in continuum-fluid models of non-equilibrium gas flows [PDF]
, 2005 In hypersonic aerodynamics and microflow device design, the momentum and energy fluxes to solid surfaces are often of critical importance. However, these depend on the characteristics of the Knudsen layer - the region of local non-equilibrium existing up

Sand transverse dune aerodynamics: 3D Coherent Flow Structures from a computational study [PDF]
, 2015 The engineering interest about dune fields is dictated by the their interaction with a number of human infrastructures in arid environments. Sand dunes dynamics is dictated by wind and its ability to induce sand erosion, transport and deposition.

Scientific Reports, 2023 AbstractComputational fluid dynamics simulations of fibrous filters with 56 combinations of different fiber sizes, packing densities, face velocities, and thicknesses were conducted for developing models that predict pressure drops across nanofiber filters. The accuracy of the simulation method was confirmed by comparing the numerical pressure drops to

Variation in aerodynamic coefficients with altitude
Results in Physics, 2017 Precise aerodynamics performance prediction plays key role for a flying vehicle to get its mission completed within desired accuracy. Aerodynamic coefficients for same Mach number can be different at different altitude due to difference in Reynolds ...

Hypersonic aerodynamics on thin bodies with interaction and upstream influence [PDF]
, 1994 In the fundamental configuration studied here, a steady hypersonic free stream flows over a thin sharp aligned airfoil or flat plate with a leading-edge shock wave, and the flow field in the shock layer (containing a viscous and an inviscid layer) is ...

Etude numérique et expérimentale de l'écoulement autour d'un rotor éolien [PDF]
, 2013 An improved model of an actuator surface is proposed, representing the flow around a wind turbine. This model was developed in conjunction with a Navier-Stokes solver using a blade element method for the calculation of power and wake development.
