Abstract: A deep drawing test is described for measuring the coefficient of friction between the cylindrical surfaces of the punch and the cup wall. The test is based on an analysis of the stress ...

Abstract: In this study, the performance of regenerative cooling system for large expansion ratio rocket engines (Ae/At ∼ 100) is investigated numerically. During combustion and gas expansion, the walls of the combustion chamber ...

Abstract: The stone columns (or granular piles) are increasingly being used as ground reinforcement elements for supporting a wide variety of structures including buildings and flexible structures. The stone columns derive their ...

Abstract: This paper deals with a study of the flexural behavior of thin, fiber-reinforced, resinoid abrasive disks. During use, these disks generally encounter a much higher ratio of flexural or bending ...

Abstract: Frontier methods quantify the energy efficiency of buildings by forming an efficient frontier (best-practice technology) and by comparing all buildings against that frontier. Because energy consumption fluctuates over time, ...

Abstract: In this numerical study, the cooling of exhaust gas issued from a rocket engine in a ground test facility has been investigated by solving the three-dimensional governing equations. Simulations have been performed by ...

Abstract: Geosynthetic reinforced piled embankment systems (GRPESs) have proven to be an effective and economical technique to address the problems posed during the construction of embankments on soft soils. In this paper, the ...

Abstract: Structural and aeroelastic analyses using beam theories by default choose a cross section that is perpendicular to the reference line. In several cases, such as swept wings with high AR, a beam theory that allows for the ...

Abstract: The design of class‐I (discrete particles) settling tanks would be more rational and economical if designed for overall particle removal rather than for an overflow rate based on the smallest particle to be removed. The ...

Abstract: The effects of temperature, pH, sludge age in the prior activated sludge process, initial sludge solids concentration, and sludge type on the rate of solids degradation during aerobic sludge stabilization are discussed. ...
