the object of this work is solubility correlation and prediction of co2 and h2s in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (ecsw eos) [haghtalab, a.,mazloumi, s. h., (2009a), fluid phase equilib.,285,96-104]. the eeos systematically is applied to describe the solubility of acid gases in various alkanolamine solutions, including mdea, mea, dea, amp...

In order to estimate Reynolds number effects on a transonic transport aircraft CFD calculations have been performed. The CFD calculations have been done solving the RANS equations on an unstructured grid for varying Reynolds number at transonic conditions. Low Reynolds number data have been extrapolated to a higher Reynolds number condition with different scaling methodologies in order to evalu...

This paper presents initial results on the aeroacoustic and aerodynamic effects of morphing trailing-edge flap 30P30N aerofoil, over five deflections (5–25°), at an 8° angle attack a Reynolds number Re=9.2×105. The Ffowcs-Williams–Hawkings acoustic analogy estimates far-field noise, whilst flow field is solved using URANS with four-equation Transition SST model. Aerodynamic simulation data for ...

PURPOSE This study aims to present flow control over the backward-facing step with specially designed right-angle-shaped plasma actuator and analyzed the influence of various scales of flow structures on the Reynolds stress through snapshot proper orthogonal decomposition (POD). METHODS 2D particle image velocimetry measurements were conducted on region (x/h = 0-2.25) and reattachment zone in...

For developing a reliable data-driven Reynold stress tensor (RST) model, successful reconstruction of the mean velocity field based on high-fidelity information (i.e., direct numerical simulations or large-eddy simulations) is crucial and challenging, considering ill-conditioning problem Reynolds-averaged Navier–Stokes (RANS) equations. It shown that frozen treatment Reynolds force vector (RFV)...
