When raindrop diameter d<1.9mm, use husky Yuqin's formula of revising:
v
T＝0.496*10
x
Wherein,
When d >=1.9mm, use the Newton's formula of revising:
Rainfall kinetic energy e calculates by following formula:
The unit of e is J/ (m
2mm), when most raindrop can reach terminal velocity, v
1can directly adopt v
tcalculate.
Compare raindrop splass speed v
1with raindrop terminal velocity v
tcan obtain, rainfall shower nozzle is when maximum height (4.5m), for the shower nozzle of different pore size, after upper water pressure is suitably regulated, most raindrop all can reach terminal velocity, now can calculate rainfall kinetic energy by terminal velocity, and terminal velocity is relevant with raindrop particle diameter, therefore measure after raindrop particle diameter, just can calculate rainfall kinetic energy.

In formula: H
ifor the measuring point rainfall on rainfall face, unit is mm;
for the average rainfall on rainfall face, unit is mm; N is that rainfall measurement is counted.
For simulating nature rainfall effectively, need meet rainfall uniformity coefficient K >=80%.During application insulator contamination loss coefficient research device, for the simulated rainfall of the same water pressure not, can, by regulating the spacing between two rainfall shower nozzles, realize rainfall uniformity coefficient K >=80%.
