Abstract: An integral variational equation can adequately describe heat, mass, and momentum transfer in a moving chemically reactive fluid. The Euler-Lagrange equations corresponding to the suggested variational ...

Abstract: High demand for formed tubular components and the necessity to increase their strength to weight ratio have established a need for new, effective, and low cost forming technologies. This work ...

Abstract: The work presented investigates numerically and experimentally a formation of high velocity liquid projectiles in the course of the unsteady water acceleration by gaseous products of a propellant ...

Abstract: This paper presents results for the minimization of fuel consumption in a batch furnace. Several different criteria are used and minimized with respect to time-dependent process and control ...

Abstract: This study was concerned with the use of the ice-air jet. It was demonstrated that at the optimal range of process conditions this jet constitutes a precision tool for selective material ...

Abstract: Water ice powder constitutes a potentially important manufacturing tool. Availability and cleanliness of this powder constitute its major advantage. It was shown that the ice particles could be ...

Abstract: The use of stationary waterjet for the removal of coating material from the substrate is investigated analytically and experimentally. In the analysis, the cleaning width as a function of ...

Abstract: The objective of this work is to investigate acceleration of a water slug by the powder explosion. The process occurs in a device termed the water cannon, which entails a barrel with an ...

Abstract: A mathematical model of cleaning with moving waterjet is established by considering the structure of waterjet and applying Springer’s semi-empirical model on material erosion due to impact of ...
