为了提高淹没磨料射流的切割能力，研制了一种用于产生空气涂层淹没磨料射流的通气护套喷嘴。通过对铝合金试件的切削试验，研究了空气涂层ASJ在浸水条件下的切削特性。本文还通过对空气包覆水射流的高速观测，研究了射流周围空气包覆层的非定常行为。基于通气腔压力的空化数和Strouhal数对空气包层射流的切割能力和空气包层射流的非定常特性进行了合理的安排。
In order to improve cutting capability of a submerged abrasive suspension jet (ASJ), a ventilated sheathed nozzle for producing an air coated ASJ has been developed. Cutting characteristics of air coated ASJs under submerged condition are provided by cutting tests with specimens of aluminium alloy. Unsteady behaviour of the air coated layer around the jet is also investigated by high speed observations of air coated water jets. The cutting capability of air coated ASJs and the unsteady behaviour of the air coated layer of the submerged jets are arranged properly by the cavitation number based on the pressure in the ventilated cavity and Strouhal Number.
