Viscous Fingering in Miscible, Immiscible and Reactive Fluids
With the Lattice Boltzmann method (using the BGK approximation) we investigate the dynamics of Hele-Shaw flow under conditions corresponding to various experimental systems. We discuss the onset of the instability (dispersion relation), the static properties (characterization of the interface) and the dynamic properties (growth of the mixing zone) of simulated Hele-Shaw systems. We examine the ...
متن کاملPotential flows of viscous and viscoelastic fluids
Potential flows of incompressible fluids admit a pressure (Bernoulli) equation when the divergence of the stress is a gradient as in inviscid fluids, viscous fluids, linear viscoelastic fluids and second-order fluids. We show that in potential flow without boundary layers the equation balancing drag and acceleration is the same for all these fluids, independent of the viscosity or any viscoelas...
متن کاملStability analysis of two-layer immiscible viscous fluids in an inclined closed tube
The present investigation is concerned with the role of bottom slope in the stability properties of two-dimensional disturbances in sheared two-layer immiscible fluids with stepwise densities. A linear analysis of normal mode instability of the interface in an inclined closed tube is carried out using full Navier-Stokes equation using Chebyshev-tau method. It has been observed that Reynolds num...
متن کاملParticulate Viscous Effects on the Compressible Boundary-layer Two- Phase F L O W over a Flat Plate
The problem of compressible boundary-layer laminar flow of a particulate suspension over a semi-infinite fiat plate is solved numerically using the finite-difference methodology. The mathematical model employed includes such effects as particle-phase viscous stresses, variable position-dependent particle slip coefficient, and general power-law viscositytemperature and thermal conductivity-tempe...
متن کاملA Novel Similarity Solution of Turbulent Boundary Layer Flow over a Flat Plate
In this paper, the similarity solution of turbulent boundary layer flow on the flat plate with zero pressure gradients is presented. By employing similarity variables the governing partial differential equations are transformed to ordinary ones with inconsistent coefficients and solved numerically with the use of Runge–Kutta and shooting methods in conjunction with trial and error procedure. Fo...
