The Dissipation Function-Based Efficiency for Turbomachinery—Part I: The Efficiency of a Cooled Turbine Row1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of coolant addition or “mixing loss” on aerodynamic performance is formulated for the turbine, where mixing takes place between gas streams of different compositions as well as static temperatures. To do this, ...
Three-Dimensional Wind Field Analysis from Dual-Doppler Radar Data. Part III: The Boundary Condition: An Optimum Determination Based on a Variational Concept
Publisher: American Meteorological Society
Abstract: The choice of the boundary condition when integrating the air mass continuity equation, is a major problem of the 3D wind field analysis from dual (or multiple) Doppler radar data. A zero vertical velocity at ground level ...
Three-Dimensional Wind Field Analysis from Dual-Doppler Radar Data. Part I: Filtering, Interpolating and Differentiating the Raw Data
Publisher: American Meteorological Society
Abstract: This paper is the first of three dealing with the three-dimensional wind field analysis from dual-Doppler radar data. Here we deal with the first step of the analysis which consists in interpolating and filtering the raw ...
Three-Dimensional Wind Field Analysis from Dual-Doppler Radar Data. Part II: Minimizing the Error due to Temporal Variation
Publisher: American Meteorological Society
Abstract: One of the major problems in three-dimensional wind field analysis from dual (or multiple) Doppler radar data resides in the non-stationary of the observed air flow within the volume sampling time which ranges typically ...
A Doppler Radar Observation of a Cold Front: Three-Dimensional Air Circulation, Related Precipitation System, and Associated Wavelike Motions
Publisher: American Meteorological Society
Abstract: This paper is based on the observation of a cold front using a C-band Doppler radar. The extent of the precipitation system associated with the front allowed collection of Doppler radar data during 12 consecutive hours. ...
Experimental and Numerical Investigation of Combustor-Turbine Interaction Using an Isothermal, Nonreacting Tracer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Understanding the interaction between the combustor and turbine subsystems of a gas turbine engine is believed to be key in developing focused strategies for improving turbine performance. Past ...
Real–Time Wind Synthesis from Doppler Radar Observations during the Mesoscale Alpine Programme
Publisher: American Meteorological Society
Abstract: A real?time and automated multiple?Doppler analysis method for ground?based radar data, with an emphasis on observations conducted over complex terrain, is presented. It is the result of a joint effort of the radar groups ...
