Numerical Investigation of Orifice Nearfield Flow Development in Oleo-Pneumatic Shock Absorbers
نویسندگان
چکیده
The flow field development through a simplified shock absorber orifice geometry is investigated using single phase Large Eddy Simulation. Hydraulic oil used as the working fluid with constant inlet velocity and an open top boundary to allow study focus on free shear layer in vicinity of main orifice. validated standard mixing dynamics. impact shape discussed regards initial growth, potential appearance cavitation bubbles. Observations are made regarding presence disturbances upstream orifice, thereby, leading notable turbulence intensity level those regions.

Conceptual Design of Single-Acting Oleo-Pneumatic Shock Absorber in Landing Gear with Combined Method
Landing gear is a structure that is mounted under the fuselage and helps the aircraft in takeoffs and landings. The most important duty of landing gear is the control of vibration exerted on the system through the shock absorber which is a common component to all the landing gear. Considering the importance of this issue, the necessity of investigating shock absorber with features such as high ...
متن کاملNumerical Investigation of Shock Tube Flow under Rarefied Conditions
Two-dimensional Direct Simulation Monte Carlo (DSMC) simulations are carried out for investigating the shock wave propagation and boundary layer effects in a shock tube flow, for a wide range of rarefied conditions. Nitrogen is used for all simulations. The Cercignani-Lampis-Lord (CLL) model of gas surface interactions is implemented to study the effects of boundary layer which develops behind ...
متن کاملNumerical Investigation of Vortex Interaction in Pipe Flow
To discover the nonlinear characteristics of pipe flow, we simulated the flow as a sum of many vortex rings. As a first step, we investigated the nonlinear interaction among a maximum of three vortex rings. The pipe wall was replaced by many bound vortices. A free vortex ring moves right or left according to the radius, and that of a particular radius keeps the initial position. The energy of a...

15 صفحه اولNumerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
