Abstract: A thin circular liquid sheet can be formed by impinging two identicalround jets against each other. The liquid sheet expands to a certain critical radial distance and breaks. The unsteady process of the formation and breakup of the liquid sheet in the ambient gas was smiulated num erically. Both liq...
Abstract: Hydraulic calculation of steady uniform flow in trapezoidal compound open channels was studied. Based on the force balance of water in each sub-section, the average velocities of the main channel, side slope and floodplain were deduced, and the lateralmomentum exchanges between the sub-sections were...
Abstract: An analys is was developed in order to study the unsteady free convection flow of an incompressible, visco-elastic fluid on a continuously moving vertical porous plate in the presence of a firs-torder chemical reaction. The governing equations were solvednumerically using an implicit finite differen...
Abstract: An analysis of the steady two-dimen sional non-Newtonian flow on a power-lawstretched surface with suction or injection was considered. The thermal conductivity was assumed to vary as a linear function of temperature. The transformed governing equations in the present study were solved numerically b...
Abstract: The influence of heat transfer and induced magnetic field on peristaltic flow of a Johnson-Segalman fluid was studied. The purpose of the present investigation was to study the effects of induced magnetic field on the peristaltic flow of non-Newtonian fluid. The two-dimensional equations of Johnson-...
Abstract: The gas temperature within hypersonic boundary layer flow is so high that the specific heat of gas is nolonger a constant but relates with temperature. How variable specific heat to influence on boundary layer flow stability is worth researching. The effect of the variable specific heat on the stabi...
Abstract: Taking the strain tensor, scalar damage variable and damage gradient as the state variables of Helmholtz free energy, the general expressions of first-order gradient damage constitutive equations were derived directly from the basic law of irreversible thermodynamics by constitutive functional expan...
Abstract: Based on the three-dmiensional Gurtin-type variational principle of the incompressible saturated porousmedia, first, a one-dimensionalm athematical model for dynamics of the saturated poroelastic Timoshenko Cantilever beam was established with a ssumptions of deformatin of the classical single phase...
Abstract: Bifurcation properties of Duffing-van der Pol System with two parameters under multi-frequency excitations were studied. It was discussed for three cases 1 λ1 was considered as bifurcation parameter, 2 λ2 was considered as bifurcation parameter, 3 λ1 and λ2 were both considered as bifurcation parame...
Abstract: A class of boundary value problem for differential equation with a turning point was considered. Using the method of multiple scales and others, the uniformly valid asymptotic expansion of solution for the boundary value problem was constructed.
Abstract: Sufficient condition of almost sure stability of two-dimensional oscillating systems under parametric excitations was investigated. The systems considered were assumed to becom posed of two weakly coupled subsystems. The driving actions were considered to be stationary stochastic processes satisfyin...
Abstract: Eigen function expansion method of solving two-dmiensional elasticity problems was proposed based on stress formulation. By introducing appropriate state functions, the fundamental system of partial differential equations of the above two-dmien sional problems was rewritten as an upper triangular di...
