RISAnalysis of Heat Transfer Oscillation and Buoyancy Effects of Supercritical R1234ze(E) Cooled in Horizontal Helically Coiled Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The helically coiled tubes (HCTs) have been attracting huge attention for enhancing the heat transfer of supercritical fluids and improving energy efficiency. Moreover, the new refrigerant R1234ze(E) has excellent environmental ...
Development of a Multiphase Flamelet Generated Manifold for Spray Combustion Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a model flame of quasi-one-dimensional (1D) counterflow spray flame has been developed. The two-dimensional (2D) multiphase convection-diffusion-reaction equations have been simplified to one dimension using ...
Experimental and Numerical Study of Volt–Ampere Characteristics of a Packed Tube Heated by Joule Heating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work is devoted to experimental and numerical studies of volt–ampere characteristics of a fixed bed heated by Joule heating. The main feature of this type of fixed bed is internal heat generation using the Joule heat. ...
Discrete-Element Modeling of Influence of Void Characteristics on Uniaxial Penetration Strength of Asphalt Mixtures
Publisher: ASCE
Abstract: This paper aims to investigate the influence of void characteristics on the uniaxial penetration strength (UPS) of asphalt mixtures using a three-dimensional (3D) discrete-element method (DEM). Three models for the uniaxial ...
Mechanical Response of Asphalt Surfaces under Moving Traffic Loads Using 3D Discrete Element Method
Publisher: ASCE
Abstract: This paper investigates the mechanical response of asphalt surfaces under moving traffic loads using the three-dimensional (3D) discrete element method (DEM). As an example of a semirigid base asphalt pavement, a discrete ...
