The invention belongs to the field of experimental devices, and discloses a crankcase ventilation system oil-gas two-phase flow experimental device. The crankcase ventilation system oil-gas two-phaseflow experimental device comprises an adjustable liquid drop generating unit, an adjustable air flow generating unit, an adjustable fuel-air mixing unit, an adjustable experimental pipeline unit and aliquid drop information acquisition and liquid film distribution measuring unit; the adjustable air flow generating unit comprises an air flow stabilization case; the adjustable fuel-air mixing unitcomprises a sealing case, a rectangular pipeline and an adjustable experimental pipeline; and the liquid drop information acquisition and liquid film distribution measuring unit comprises a high-speedcamera and a capacitance tomography device. The flowing process of a gas-oil mixture in a crankcase ventilation system is accurately simulated, and control on the flowing direction and the flowing speed of the gas-oil mixture is achieved through the adjustable experimental pipeline unit, so that machine oil liquid drop information and liquid film spatial distribution condition of a boundary placein the flowing process of the gas-oil mixture, and condition that machine oil liquid drops are separated from the gas-oil mixture in the flowing process are obtained in real time.
Description
technical field [0001] The invention belongs to the technical field of test devices, and more specifically relates to a crankcase ventilation system oil-gas two-phase flow test device. Background technique [0002] The crankcase ventilation measure is an important measure to ensure the normal operation of the diesel engine. The oil-air mixture inside the crankcase is released through the crankcase ventilation system to reduce the pressure of the oil pan. There are oil droplets in the oil-air mixture flowing through the crankcase ventilation system. In order to reduce oil consumption and reduce environmental pollution, it is necessary to study the flow process of oil-air mixture in the crankcase ventilation system. However, the structural size parameters of the crankcase ventilation system are determined according to the specific conditions of the engine, so it is very difficult to directly study the system as a whole. According to the flow characteristics of the oil-air mix...
