The flow is described by the incompressible Navier–Stokes equations and numerically solved by the parallel adaptive finite element package DROPS. Three different optimization algorithms for the solution of the parameter estimation problem are compared from within the EFCOSS environment. In this ...
performance. Moreover, for some problems, explicit solutions do not work at all; without an implicit solver, some simulations cannot be implemented. An example is the Poisson-pressure equation that arises in the solution of the Navier-Stokes equations for fluid flow. See Figures...
The so-called “Reynolds equation” provides essentially a prediction of the pressure distribution in the thin film lubrication, which is derived from the Navier–Stokes and continuity equations for incompressible flows [5]. Several approaches have been proposed to solve the Reynolds partial ...
Because the Navier-Stokes equation is a high-index differential algebraic equation, options are specified to time-integrate the equations efficiently. The maximum difference order of the time integrator is reduced to minimize the number of rejected steps. The time-dependent boundary conditions are diffe...
The Navier–Stokes equations advance in time through the fractional step method, implemented in 4 key steps. First, the right hand side terms are evaluated numerically, calc_transeq_rhs in Fig. 1 and integrated in time (with e.g. Runge–Kutta or Adams–Bashforth schemes), generating an ...
This is in turn suitable for solving fluid flow and heat transfer problems governed by Navier–Stokes(N–S) equations on geometries having nonuniform and nonorthogonal curvilinear grids. The newly proposed scheme has been applied to solve general second order partial differential equation having ...
