RISDynamic Performance Characteristics of a Porous Volumetric Solar Receiver Under Transient Flux Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The solar flux incident on a volumetric receiver is inherently unsteady, resulting in high thermal stresses, fatigue failures, and reduced component life. The knowledge of transient response characteristics of a porous ...
Rehabilitation of RC Beams with Web Openings Using Alkali-Activated Fiber-Reinforced U-Jacket
Publisher: ASCE
Abstract: The structural performance of a damaged web opened beam repaired and strengthened by U-shaped jacketing with fiber-reinforced geopolymer concrete (FRGC) is evaluated. Reinforced concrete (RC) beams with openings in the ...
Carbonation in Concrete Infrastructure in the Context of Global Climate Change: Model Refinement and Representative Concentration Pathway Scenario Evaluation
Publisher: American Society of Civil Engineers
Abstract: A number of recent studies have identified and begun to quantify increased susceptibility of the infrastructure to climate change–induced carbonation of reinforced concrete. In this paper, the results of a study are presented ...

Pore Scale Numerical Investigation of Mixed Convection From an Isolated Heat Source in a Channel With a Porous Insert
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mixed convection heat transfer in a channel filled with porous medium and containing an isolated heat source at the bottom wall is studied in this work. The porous medium is assumed to be made of circular cylinders and is ...
Thermo-Fluid Design Simulation of Nd3+ POCl3 Transverse Flow Liquid Laser Cavity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) based thermal design of a transverse flow optical cavity is carried out for 1 kW Nd3+ POCl3 liquid laser source to investigate temperature and velocity distribution in the optical pumping ...
