air current, current of air, wind - air moving (sometimes with considerable force) from an area of high pressure to an area of low pressure; "trees bent under the fierce winds"; "when there is no wind, row"; "the radioactivity was being swept upwards by the air current and out into...
Conceptually, we define abnormal net hiring as the difference between the actual change in a firm's labor force and the expected change based on fundamental economic factors. Our primary estimate of expected net hiring is based on model (4), which is a regression of the percentage change in ...

Under the strong centrifugal force generated by the high-speed rotating turbine, the materials are separated and the fine particles which meet size requirements through the classifier impeller gap into the cyclone separator or the dust collector, ...
Thus, a solar collector coupled with the solar chimney is capable to provide sufficient cooling force for a coupled geothermal system. For the forced cooling modes, the air flow rate was constant with a value of 2750 m3/h. For the thermal comfort analysis Predicted Mean Vote (PMV) and ...
