A Review Paper on: Containment Test and Impeller Burst Simulation using Explicit Dynamics

Abstract

Containment test is done for ensuring the safety of turbocharger by checking the ability of the turbine and compressor housing to retain all the fragments within it, in case of wheel burst. For inducing impeller burst, an impeller with purposely provided slot on the back face of the impeller is assembled in turbocharger and operated at target speed. Experimental testing involves various iterations to be performed for successful burst to occur i.e. to obtain correct slot dimensions of the impeller to burst at target speed, resulting in expensive and time consuming test. Thus, to avoid the experimental iterations of containment testing, Finite Element simulation method can be used. This paper presents the literature survey on containment testing, methodology used for simulating containment test and impeller burst. Based on literature survey, various parameters can be considered to develop a methodology to simulate impeller burst.
