Simple Approach for Evaluation of Abrasive Mixing Efficiency for Abrasive Waterjet Rock Cutting

The abrasive mixing variables, such as the and water flow rates focus geometry parameters, determine profitability of an waterjet system. In this study, efficiency characteristics in rock cutting were investigated. To demonstrate comprehensively reduction due to collision during mixing, chance was expressed distance between particles focus. then assessed by utilizing empirical relationship experimental results developed model. Based on particle density velocity, closer showed higher chances collision, thus yielding a reduced performance. Using model, optimum rate performance systems can be estimated. This model used for design selection cost-effective use waterjets.
