RISQuasi-Steady Water Droplet Heat- and Mass-Transfer With Ventilation, Blowing, and Radiation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A quasi-explicit analytical model of quasi-steady (QS) water droplet heat- and mass-transfer, including radiation, in a prescribed gaseous environment with velocity slip, i.e., gas flow around the droplet, and high ...
Pressure Drop Predictions for Laminar Fully Developed Flows of Purely Viscous Non Newtonian Fluids in Circular Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides the results of numerical calculations of pressure drops and centerline velocities for laminar fullydeveloped flows of nonNewtonian fluids in circular ducts. The particular nonNewtonian fluid model ...
Mixed Boundary Layer Skin Friction and Heat Transfer With Abrupt Transition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the form that is commonly published in introductory textbooks, the classical problem of skin friction and heat transfer for a mixed laminar–turbulent boundarylayer flow on a flatplate with an abrupt transition is ...
Phase-Correcting Data Assimilation and Application to Storm-Scale Numerical Weather Prediction. Part II: Application to a Severe Storm Outbreak
Publisher: American Meteorological Society
Abstract: A scheme to correct phase errors in numerical model forecasts using Doppler radar, radiosonde, profiler, and surface data is demonstrated to improve forecasts in a complex severe thunderstorm situation. The technique is ...
Photographs of a Funnel-Producing Indented Cloud-Base Swirl
Publisher: American Meteorological Society
Abstract: An interesting swirl in the cloud base of a severe thunderstorm near Denver, Colorado, is documented with photographs and Doppler radar velocity measurements. The swirl, which produced two funnel clouds, may have been an ...
Water Evaporation and Condensation in Air With Radiation: The Self-Similar Spalding Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several simple ways of improving the accuracy of Spalding model predictions over common textbook conventions for air/water evaporation/condensation problems are illustrated using open-literature examples. First is the ...
Phase-Correcting Data Assimilation and Application to Storm-Scale Numerical Weather Prediction. Part I: Method Description and Simulation Testing
Publisher: American Meteorological Society
Abstract: An objective method of determining and correcting phase or position errors in numerical weather prediction is described and tested in a radar data observing system simulation experiment (OSSE) addressing the forecasting ...
A Conservation-Based Transitional Boundary Layer Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple, flow-physics-based model of flat-plate, transitional boundary layer skin friction and heat transfer is presented. The model is based on the assumption of negligible time-, spanwise-, and streamwise-average ...
Theoretical Modeling of Levitated Clusters of Water Droplets Stabilized by Infrared Irradiation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper shows how clusters of radiation-stabilized water droplets levitated in an upward flow of air and water vapor above a heated water surface can be modeled using Spalding's self-similarity theory of heat and mass ...
