Test stand for optical measurements of flow conditions of fluids

摘要

Test stand for optical measurements of flow conditions of fluids, wherein the flow of a vortex flow, in particular a tumble - and / or swirling flow is formed, in particular for investigations of charge movements in the case of a change in the combustion chamber of an internal combustion engine, wherein the test stand a comprises a box and a cylinder, the assembly consisting (14), on the upper end face a cylinder head (10) or an inlet channel model can be mounted with gas exchange valves, and the module (14) consists of two separate and transparent parts (1; 2) is formed which have different diameters and dimensions and are arranged in one another, wherein an inner cylinder (1) a shorter length than an outer box (2), on its upper end face is designed to be open, at this upper end face with the cylinder head (10) or the inlet channel model in operative connection, and on its lower end face for swirling flows open and closed for tumbling flows with two lateral openings and the outer box (2) on its upper and lower end face in each case closed design..
