Thermal gradients during the early,non-isothermal period of near-field evolution in a KBS–3 repository for nuclear wastes could alter the mineralogy of the bentonite buffer and cause the constituent clay particles to become cemented together by mineral precipitates.

Numerical modeling of vertical 2D unsteady flow and suspended material distribution;

Study on the influences of daily regulation unsteady flow in hydroelectric project to mooring force;

Numerical simulation of unsteady flow in Xiangjiaba Hydropower Project;

According to perturbation method in hydrodynamics,the differential equations including continuity equation and movement equation of transient flow in open channel are transformed into polynomials.

But its transient flow problem hasn t been well resolved.

Based on the differential equations of the transient flow in conduit under pressure and combined with the specific boundary condition of Wanniuba Water Power Station,a numerical model is constituted with characteristic method,which is used to simulate the transients of sudden load rejection in water power stations.
