RESUMO

The lock flow consists of two immiscible fluids initially stagnant in a two-dimensional rectangular channel, and separated by a gate. Mutual penetration develops after the gate is suddenly withdrawn and two gravity driven fronts propagate along the upper and lower surfaces of the channel. It is proposed to calculate the front propagation velocities and run-out lengths as functions of time.
