RISTemperature Effects on Single Bubble Collapse and Induced Impulsive Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In relation to the temperature effect in cavitation damage, the collapse of a single bubble in water over a wide range of temperatures was experimentally studied. A spark-induced bubble was ...
Proposed Practical Methods to Estimate Rock Strength and Tooth Wear While Drilling With Roller-Cone Bits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The authors have previously developed and proposed methods to estimate the in situ rock strength and tooth wear while drilling with roller-cone bits [Karasawa et al., 2002, ASME J. Energy ...
Methods to Estimate the Rock Strength and Tooth Wear While Drilling With Roller-Bits—Part 2: Insert Bits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: New methods to estimate both the rock strength and tooth wear while drilling with roller-bits were developed and proposed in Part 1. These methods were derived from the results of drilling ...
Methods to Estimate the Rock Strength and Tooth Wear While Drilling With Roller-Bits—Part 1: Milled-Tooth Bits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes new methods to estimate both the rock strength and tooth wear while drilling with roller-bits. Laboratory drilling tests were conducted to obtain the penetration rate, bit ...
