CFD Simulation of Gas-Water Two-Phase Flow in Turbocharger
A turbocharger is widely used by industry as an efficient thermal performance enhancement device, and its efficiency is often dependent on the conditions and properties of the working fluid. One industry problem is the use of low-grade diesel, that produces various combustion products, and thus causes blade throat blockage, blade corrosion, damage, etc. At present, one solution is to attach an ad hoc online water washing system that operates daily to remove in part any accumulated solid deposits. While the method works well, an in-depth understanding of the washing mechanism is still quite limited. Complementary to essential in-house rig testing, it is now feasible to carry out numerical simulation of flow thus to provide further understanding. A combined experimental and numerical study of gas-water two-phase flow in turbocharger has therefore been proposed with some results presented here.
