  • Practical Considerations in Pump Suction Arrangements

    2021-1-16 · Large eddy simulation (LES) is an efficient technique to simulate turbulent flows of practical interest, based on the elimination of flow scales smaller than a characteristic length and direct resolution of the largest scales. There is a variety of subgrid-scale models available in the literature to describe the turbulence in small scales, with different levels of complexity and computational ...

  • The Horizontal Directional Drilling Process

    2015-8-6 · Downhole mechanical cutting action required for harder soils is provided by downhole hydraulic motors. Downhole hydraulic motors, commonly referred to as mud motors, convert hydraulic energy from drilling mud pumped from the surface to mechanical energy at the bit. This allows for bit rotation without drill string rotation.

  • BLASTING TECHNICAL INFORMATION - MC Finishing

    2021-6-28 · The air jet is 1/2 the ID of the nozzle and as the air stream is passed through both, it creates a low pressure which sucks the media from the hopper into the air stream. The media acceleration distance is very short ( from the nozzle to the workpiece-approximately 4 to 14”).

  • WELDING OF STAINLESS STEELS AND OTHER JOINING

    The compressor uses the high steam pressure to increase the kinetic energy and the steam is ejected at high speed from the nozzle. This jet effect mixes the steam and the vapour from the product and compresses the mixture to a higher pressure. Using a thermocompressor together with a multiple-effect unit optimizes the energy balance. Process flow
