RISAerothermodynamic Assessment of Spiked Configuration for Drag Reduction at Hypersonic Speeds
Publisher: ASCE
Abstract: Aerothermodynamic analysis was performed for blunt-body configurations with spikes mounted to determine drag reduction effectiveness. In-house perfect gas and chemical nonequilibrium solvers were utilized. The analysis ...
Heat Transfer and Fluid Dynamics Study in Solar Air Heater Employing Impinging Circular Air Jet Array for Effective Jet Stability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This experimental and numerical investigation is intended to increase heat transfer, reduce pumping power, and present important guidelines on the use of confined submerged air jet impingement in solar air heater designs ...
Impact of Particle Packing Method of Design Mix on Fracture Behavior of Concrete: Critical Analysis
Publisher: ASCE
Abstract: This paper discusses the effect of the particle packing method (PPM) of mix design on the fracture behavior of concrete. A three-point bending (TPB) test was performed on single-edge notched beam for three different sizes. ...
Synthesis and Characterization of the Paraffin/Expanded Perlite Loaded With Graphene Nanoparticles as a Thermal Energy Storage Material in Buildings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Various properties of the paraffin have made them compatible to be incorporated in the building materials for improving the latent heat storage capacity of the building envelope. However, the poor thermal conductivity of ...
Pb-Zn Smelter Residue (LZSR) Stabilized Using Low-Carbon, Low-Cost Limestone–Calcined Clay Cement: Leachability, Chemical Speciation, Strength, and Microstructure
Publisher: ASCE
Abstract: The low-carbon and low-cost cement known as limestone–calcined clay cement (LC3) is used in this study to investigate the immobilization potential of Pb-Zn smelter residue (LZSR). The performance of LC3 treatment on LZSR ...
