The pressure-free two-fluid model (PFTFM) is a recent reformulation of the one-dimensional (TFM) for stratified incompressible flow in ducts (including pipes and channels), which pressure eliminated through intricate use volume constraint. disadvantage PFTFM was that volumetric rate had to be specified as an input, even though it unknown quantity case periodic boundary conditions. In this work,...
in this paper, nonlinear vibration and instability response of an embedded pipe conveying viscose fluid is investigated. the pipe is considered as a timoshenko beam embedded on an elastic foundation which is simulated by spring constant of the winkler-model and the shear constant of the pasternak-model. the external flow force, acting on the beam in the direction of the flexural displacement is...
A novel computational fluid dynamics and molecular kinetic theory (CFD-MK) method was developed to simulate the impingement of a nanodroplet onto a solid surface. A numerical solution of the Navier–Stokes equation using a volume-of-fluid (VOF) technique was used to model nanodroplet deformation. Dynamic contact angle during droplet impact was obtained by molecular kinetic theory. This dynamic c...
