Slurry Jet Erosion Test Rig: A Review of Erosive Particles Induction Methods and Its Test Parameters

Abstract

Slurry erosion as problem was identified during World War II in oil and munitions industries. Industrial components were severely damaged due to interaction with fluid and particles inclusion, resulted in huge financial losses. To evaluate the erosion, slurry erosion test set-ups were developed. In this article, slurry jet erosion test set-ups developed are reviewed and are classified based on the erosive particles induction method. Each test set-ups are named after the initial test set-up originators, namely Levy, Turenne, Hutchings, and Thapa test method, respectively. Test set-ups are further categorized into premixing and postmixing type and recirculation and non-recirculation of slurry type. For each test method, number of researchers adopted the test method and number of research articles published by the researchers are illustrated. Emphases are made on the erosion test parameters viz velocity, nozzle diameter, concentration, and erosive particles type and size. From the literature, it is observed that Turenne test method is the most popular test method, while Levy test method is the less popular method; based on adoption of test method by the researchers. For the test parameters, Thapa method is with high velocity (117.3 m/s) while Hutchings method is with low velocity (1.5 m/s) and Hutchings method is with high concentration (40 wt%) while Thapa method is with the lowest concentration (0.0015 wt%).
