| Abstract: | Based on the experiment on a model, the flow characteristic of gas in a tongue-repelling-board variable geometry turbine casing is investigated. The flow distribution is visualized by using thread method and tincture method which is newly developed by the authors. The working mechanism of this type of turbocharger is analysed. The test results are compared with the computer calculation results, and the conclusion is satisfactory. Theoretical basis is supplied for the design and optimization of this variable geometry turbocharger. |
