Bridging the power gap An alliance between Cummins and Komatsu provides an intriguing prospect to the industrial engine market with the new QSK78 industrial engine. Large eddy simulation in hydraulic valves Cavitation in hydraulic spool valaves involves large-scale vortical structures in an unsteady submerged jet. According to engineers from Purdue University, curent CFD approaches do not accurately predict these unsteady vortices, nor do they properly account for bubble-dynamics/flow-structure interactions. Proving heavy-vehicle performance The Nevada Automotive Test Center and Mechanical Dynamics joined forces to redesign and improve the drivetrain, frame, steering, and other subsystems of a heavy-duty military-vehicle for the USMC. Tying it all together GPS. Engine diagnostics. Wireless communications. So much technology. So many voices. Is it a chorus of the Tower of Babel?
