摘要： PURPOSE:To form easily a flow with a uniform distribution of velocity, by installing a distribution plate which causes a large pressure loss in a fluid passage to eliminate the presence of dead zone when fluids are diffused from a fluid inlet into a passage having a larger sectional area. CONSTITUTION:A distribution plate 2 is disposed in a fluid passage in a diffuser 1 so that the pressure drop caused by the fluid when it passes through the distribution plate 2 is much larger than that caused by the fluid when it flows radially outwardly through the space 3 between the plate 2 and a fluid inlet 5. The distribution plate 2 is made of porous plate of sintered metal etc., having pores with a diameter of 3-7mum, while the depth of the space 3 is made 5mum-1cm to make the pressure loss within the space 3 sufficiently small. As a result, on both sides of the distribution plate 2, no change in concentration of the fluid occurs and the fluid does not separate from said plate, causing a good piston flow of the fluid thereafter.
