Description

technical field [0001] The invention relates to a high-voltage electric transient high-speed water jet generator and a curved boundary wall pressure load measuring device, belonging to the research field of underwater explosion experiments. Background technique [0002] Bubble jet load of underwater explosion is an important part of wall pressure load of near-field underwater explosion. Due to the "attraction" effect of the wall, the velocity of the water-air interface at the end of the underwater explosion bubble away from the wall is greater than the velocity of the water-air interface near the wall, which induces a high-speed water flow, which will break through the bubble and shoot to the wall at high speed Generates bubble jet loads. The duration of the underwater explosion bubble jet is short, but the jet velocity is extremely high, and the action surface is small, which can cause very serious local damage to the ship structure. The bubble jet load of underwater expl...
