Assessing Downburst Kinematics Using Video Footage Analysis

Atmosphere
Measurements of downburst outflows using standard meteorological instruments (e.g., anemometers) are rare due to their transient and localized nature. However, video recordings of such events are becoming more frequent.

Establish Feasibility for Providing Passive Cooling With Solar Updraft and Evaporate Downdraft Chimneys

, 1987
Natural draft towers can be used for cooling and ventilating structures. From an operational perspective, the downdraft evaporatively cooled tower is preferred for a dry climate. Solar chimneys, when used alone, tend to require an excessively large solar

Experiment on the Displacement Ventilation and Cooling Ceiling System with the Film

Zhileng xuebao, 2011
Currently displacement ventilation(DV) and cooling ceiling (CC) system has two main disadvantages: condensation when the radiant panel temperature is lower than the dew point temperature of air around it, and the downdraft from the cooling ceiling ...
