Flow within thick liquid films present owing to capillary effects in the pore space is of key importance in many multiphase flow applications in porous media, for example, drying or oil recovery processes. The viscous resistance to the flow is a key parameter for modelling fluid transport in such situations. It is well known for liquid films wetting the corners of tubes of polygonal cross-secti...
Allelopathic effects of aqueous extract of pagoda tree and creeping jenny on five crop plants including wheat (Triticum aestivum), barley (Hordeum vuIgare), corn (Zea mays), millet (Pennisetum americanum) and chickpea (Cicer arietinum) were investigated in a series of experiments conducted at the faculty of Agriculture, SB University of Kerman, Iran. Experiments were based on RCBD with 3 replic...
We consider a mechanical system that is comprised of three parts: rigid outer shell with spherical cavity, core inside this and an intermediate layer liquid between the shell. Such model provides adequate description behavior wide variety celestial bodies. The centers inner liquid’s boundaries are assumed to coincide. Assuming viscosity high, we obtained approximate solution Navier–Stokes equat...
A certain level of strychninization induces in Asterina reversal of geotropism from the normally geonegative movement to a persistent downward creeping. The effect of an attached float producing upward pull is to induce upward creeping, under these conditions, whereas normally it leads to downward movement. This reversal cannot be regarded as due to a mere intensification of the sensory effect ...
Eddy-viscous modeling and the topology of extreme circulation events in three-dimensional turbulence
We discuss the role of particular velocity field configurations – instantons, for short which are supposed to dominate flow during occurrence extreme turbulent circulation events. Instanton equations, devised stochastic hydrodynamic setup homogeneous and isotropic turbulence, applied interpretation direct numerical simulation results. able in this way model time evolution events a broad range s...
