Analysis of Drying Front Propagation and Coupled Heat and Mass Transfer During Evaporation From Additively Manufactured Porous Structures Under a Solar Flux
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drying front propagation and coupled heat and mass transfer analysis from porous media is critical for soil–water dynamics, electronics cooling, and evaporative drying. In this study, de-ionized water was evaporated from ...
Combined Visualization and Heat Transfer Measurements for Steam Flow Condensation in Hydrophilic and Hydrophobic Mini Gaps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Condensation enhancement was investigated for flow condensation in minichannels. Simultaneous flow visualization and heat transfer experiments were conducted in 0.952mm diameter minigaps. An open loop steam apparatus was ...
Vibration-Enhanced Droplet Motion Modes: Simulations of Rocking, Ratcheting, Ratcheting With Breakup, and Ejection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Power plant water usage is a coupling of the energy–water nexus; this research investigates water droplet motion, with implications for water recovery in cooling towers. Simulations of a 2.6 mm-diameter droplet motion on ...
Evaporation Mechanisms and Heat Transfer in Porous Media of Mixed Wettabilities With a Simulated Solar Flux and Forced Convection Through the Media
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental apparatus was designed to study the impacts of wettability on evaporation of water from Ottawa sand. Evaporation rates were measured for: (1) a 5.7-cm-thick layer of hydrophilic Ottawa sand; (2) a 5.7-cm-thick ...
Heat and Mass Transfer in the Food, Energy, and Water Nexus—A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engineering innovations—including those in heat and mass transfer—are needed to provide food, water, and power to a growing population (i.e., projected to be 9.8 × 109 by 2050) with limited resources. The interweaving of ...
