air discharge

air discharge

[′er ′dis‚chärj]
(geophysics)
A form of lightning discharge, intermediate in character between a cloud discharge and a cloud-to-ground discharge, in which the multibranching lightning channel descending from a cloud base does not reach the ground, but succeeds only in neutralizing the space charge distributed in the subcloud layer.
A type of diffuse electrical discharge occasionally reported as occurring in the region above an active thunderstorm.

Classic installation mistakes are: insufficient space above or in front of condenser air discharge which causes recirculation and high pressure faults...dramatic under sizing of the dryers when forgetting that cooling water and ambient air in summer is at far higher temperatures than in winter...wrong power supplies are amazingly frequent.
The authors extended the work into developing empirical correlations to determine the maximum allowable charge, release height, air discharge height and direction, mixing effectiveness, air discharge area and flow rate and desired post-ventilation time when a leak incident occurs [7].
The increase in the ionization of gas in the air discharge gap of the DES will result in increase in the average specific electric conductivity [[gamma].sub.ce] of the electron-ion plasma of the channel of the arc under investigation.
This includes 61000-4-2 (ESD): air - 15kV, contact - 8k, exceeding level 4, and handles 10kV contact and 25kV air discharge. It also includes 61000-4-4 (EFT): 40A - 5/50ns and IEC 61000-4-5 (surge).
The redesigned Duratherm Max water system line incorporates a top air discharge to direct waste heat away from personnel, increased mechanical compartment ventilation, greater access to components for maintenance and improved overall performance, according to the company.
Air discharge is the other, where an ESD test gun is brought close to the DUT until a discharge occurs.
The experiment results state that: a) in proportion to negative pressure, air discharge entering flow increases as flow discharge increases.
For the new blower fan, the wing blades of the fan are re-shaped to best suite the wind flow, which allowed the new fan to become 15 percent smaller and consume 20 percent less power, yet maintaining high air discharge capacity.
Periodically, there is an air discharge noise from the drain port eliminating accumulated fluids in the pre-filters and receiver tank, and a silencer kit is included to minimize the drain discharge noise.
Heating, using this control system, is provided at a fixed airflow (the minimum rate supplied for cooling), and air discharge temperature is modulated by changes in the reheat coil output.
