RISNumerical Simulation of the Effect of Rib Orientation on Fluid Flow and Heat Transfer in Rotating Serpentine Passages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of rib orientation on flow and heat transfer in a four-pass square channel with skewed ribs in nonorthogonal-mode rotation was numerically studied by using omega-based Reynolds stress model (SMC−ω). Two cases ...
A Novel Approach for Performance Analysis of Air–Air Wickless Heat Pipe Heat Exchanger
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wickless heat pipe heat exchangers (HPHE) consistently showed instabilities and omits many experimental tests. The performance of a heat pipe is governed by many parameters, and the effects of which may influence each ...
Pullout Bond Properties of Fiber-Reinforced Polymer Tendons to Grout
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of pullout bond tests on fiber-reinforced polymer (FRP) tendons embedded in cement mortar filled steel tubes. The pullout test program involved four types of FRP bars, three types of grouts, ...
Effect of the Heat Pipe Adiabatic Region
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main motivation of conducting this work is to present a rigorous analysis and investigation of the potential effect of the heat pipe adiabatic region on the flow and heat transfer performance of a heat pipe under varying ...
Behavior of GFRP Reinforcing Bars Subjected to Extreme Temperatures
Publisher: American Society of Civil Engineers
Abstract: Corrosion of steel reinforced concrete members has stimulated the research on fiber-reinforced polymers (FRP) to be used as an internal reinforcement for concrete structures. The behavior of glass fiber-reinforced polymer ...
Physical, Mechanical, and Durability Characterization of Preloaded GFRP Reinforcing Bars
Publisher: American Society of Civil Engineers
Abstract: This paper presents the physical, mechanical, and durability characterization of glass fiber-reinforced polymer (FRP) (GFRP) bars subjected to different tensile stress levels. FRP bars were first loaded at levels up to 20, ...
Effects of FRP Reinforcement Ratio and Concrete Strength on Flexural Behavior of Concrete Beams
Publisher: American Society of Civil Engineers
Abstract: Corrosion of the steel reinforcement in a cold and saline environment leads to the overall deterioration of reinforced concrete structures. To avoid such deterioration, fiber-reinforced polymers (FRP) rebars are used in ...
Numerical Simulation of the Effect of Channel Orientation on Fluid Flow and Heat Transfer at High Buoyancy Number in a Rotating Two-Pass Channel With Angled Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Convective heat transfer in a rotating two-pass square channel with 45 deg ribs is numerically investigated to simulate turbine blade cooling operation under extreme design cooling conditions (high rotation number, high ...
Feasibility Study of Long-Term Dual Tank Photovoltaic/Thermal Indirect Parallel Solar-Assisted Heat Pump Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel dual tank photovoltaic/thermal (PV/T) indirect parallel solar-assisted heat pump system was investigated in this paper, which filled a gap in the literature. Furthermore, a long-term performance study analysis was ...
Analysis of the Evolution of the Structure of a Surface With Pyramidal Asperities in Contact With a Hard and Smooth Plane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research deals with the evolution of the structure of the sapphire–brass interface due to the variation of contact pressure. This evolution primarily affects the essential parameters that govern the thermal contact ...
