英文摘要	The head front location as the function of time for the turbulent g ravity cur rent of lock release type was firstly derived by CFD approach in this paper. The adopted Renormalization Group (RNG) k-Xmodel for Reynolds-stress closure proved to be seccessful in characterizing the time-dependant current with transitional and highly localized turbulence. Consistent with well known experimental observations, the numerical results show that the gravity current passes through two phases, an initialslumping phase in which the current head adv ances steadily, and a second self-similar phase in which the front velocity decreases in the form of negative third power of the time after release.; EI; 0; 3; 380-384; 15
