BENCH TEST, FOR THE CHARACTERIZATION OF A FLOW OF A TWO-PHASE FLUID

摘要

The invention provides a test bench for characterizing a flow of a two-phase fluid, the test bench comprising a fluid tank, a first pump suitable for taking fluid from the tank and for feeding first and second lines connected in parallel, each line being provided in succession, from upstream to downstream in the flow direction of the fluid, with: injection means for injecting air into the fluid; measurement means suitable for providing information about the proportion of the vapor phase relative to the liquid phase of the fluid; and a second pump or a Venturi.

1. A test bench for characterizing a flow of a two-phase fluid, the bench comprising a fluid tank, a first pump suitable for taking fluid from the tank and for feeding first and second lines that are connected in parallel;
the first line being provided in succession, from upstream to downstream in the fluid flow direction, with: first means for injecting air into the fluid; first measurement means suitable for providing information about the proportion of vapor phase relative to the liquid phase of the fluid; and a second pump suitable for simulating a turbine engine fuel pump, in particular a low pressure pump of a turbine engine; the second line being provided in succession, from upstream to downstream in the flow direction of the fluid, with: second means for injecting air into the liquid, second measurement means suitable for providing information about the proportion of the vapor phase relative to the liquid phase of the fluid; and a suction-generator member, e.g. a Venturi.
