RISFast Pyrolysis of Biomass Pellets Using Concentrated Solar Radiation: A Numerical Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since the 1990s, mountain pine beetles have infested mature pine trees in the forests of western North America. Fast pyrolysis is an encouraging method to convert the beetle killed pine trees into biooils. In this study, ...
Building Vibration Control by Active Mass Damper With Delayed Acceleration Feedback: Multi-Objective Optimal Design and Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The building structural vibration control by an active mass damper (AMD) with delayed acceleration feedback is studied. The control is designed with a multi-objective optimal approach. The stable region in a parameter space ...
Stability Optimization and Analysis of a Bidirectional Shaft Extension Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is to solve the problem of poor stability of bidirectional shaft pumps, under reverse and low-head condition. In this study, computational fluid dynamics (CFD) calculations are carried out and verified by model ...
Degradation of P-Nitrobenzoic Acid and 4-Chlorobenzoic Acid by Catalytic Ozonation with Modified Birnessite-Type MnO2 as Catalyst
Publisher: American Society of Civil Engineers
Abstract: Bir-MnO2 was synthesized through a hydrothermal method and modified into H-Bir by nitric acid acidification. The mechanism of its action in ozonation was explored by characterization. H-Bir possessed more oxygen vacancies ...
