Numerical analysis of parts of the installation for transporting the mixture. The mixture consists of sand, stones and water. The analysis concerns the possibility of reducing the flow velocity of the mixture in the installation by means of installing the blades. The article presents an analysis of 10 blades that have been simulated. Speed distributions are presented after passing through the blades and determined which slows the speed of the mixture to the best possible extent.

Shock Loss

To get the required power, a procedure for starting an engine is required. For an engine of the large ship or land-based power plant, two kinds of mechanisms exist: one is to use an electric motor and the other air-starter. As one of the starting methods of heavy-duty engines, the air-starter gives rotating power from the blade lifting force by the compressed air flow through the turbine to rotate the stopped engine. Since the air turbine has a large weight-to-power ratio, simple structure and is spark-free, many heavy-duty engine are equipped with this device for their starting process. In order to get high enough power required to rotate the engine up to sufficient speed in a short time, high instantaneous torque is required. An impulsive supersonic turbine can be applied for this purpose. In this case, an one-stage air turbine with a minimum length convergent-divergent nozzle and transition arc shaped rotor was utilized to reduce shock loss. The performance of the desired turbine is evaluated numerically and compared with experimental results. The spin-down test is performed to estimate the performance of the designed turbine and numerical analysis is performed using the commercial tool ANSYS CFX.
