Summary of Expertise:

Listed with other top experts in: 

ABRASIVE JET CUTTING. Expert is an expert in the field of water jet technology and has contributed to the literature in this area. He follows current advances in his position as the President of the Waterjet Technology Association and editor of the association's newsletter "Jet News."

ABRASIVE WATERJET. Expert initiated research at the US Bureau of Mines on the application of abrasive waterjets. This research included a study of the thermodynamics of the entrainment of abrasives, the collimation of the abrasive stream downstream of the mixing tube, the distribution of abrasives in the stream, the velocity of abrasive particles, and the energy of the abrasives' impact onto the target. He has also integrated abrasive jets into mining machines.

WATERJET CUTTING; WATERJET CUTTING DEVICE. Expert was the lead researcher in hydraulic mining at the US Bureau of Mines for over 25 years. His research dealt intensively with cutting earth materials with waterjets. He is familiar with the literature in this field and has written several papers dealing with waterjet cutting in mining. Expert has worked with full scale and prototype hydraulic mining machinery. After iterative cycles of equipment building, testing, and modifying, Expert led the commercialization of the borehole miner, the waterjet perforator for wells, and the abrasive jet drill. He consults with engineers on problems in waterjet cutting on a regular basis.

WATERJET SAFETY. Understanding the dangers involved with improper use of waterjet technology, Expert has relied on his experience to recommend safe waterjet operating practices. He is the Chairman of the Safety Committee of the Waterjet Technology Association. This committee published the safety manual "Recommended Practices for the Use of Hand-Held Waterjetting Equipment," which is recognized as the authoritative safety manual for waterjetting.

CRYSTALLINE INTERFACE ADHESION. While at the US Bureau of Mines, Expert conducted research on adhesion forces operating at the interfaces between minerals. He extracted bicrystal samples from rocks by microdrilling, measured the tensile strength of the bicrystal interfaces, and studied the fracture surfaces of the bicrystal planes. The results of this study were published in a Bureau of Mines report in the International Journal of Mining Sciences and Geomechanical Abstracts.

BOREHOLE MINING. Expert is knowledgeable of mining subterranean minerals from the surface through borehole by remote control. He instituted research in borehole mining at the US Bureau of Mines in 1972 as was the lead researcher in this field until the office closed in 1996. Expert directed the design, fabrication, and field testing of four borehole mining machines. One of these borehole miners was awarded Industrial Research Magazine's IR 100 awards as one of the 100 best new products of 1980.
