ESTIMATION OF IMPACT FOULINGS OF CHARGE AIR COOLER’S HEAT-EXCHANGING
SURFACE ON THEIR HEAT ENGINEERING EFFICIENCY
A.A.
Gogorenko
The
method of determination the impact of thermal resistance foulings
layers of charge air cooler’s heat-exchanging surface on the heat-transfer
coefficient is presented. In the experiment the physical features of foulings from the air are improved. The experimentally
tested, that impact of fouling layer on the heat-exchanging surface from the
air on efficiency charge air cooler is insignificant. More considerable impact
of fouling from the water on the changing of charge air cooler’s with the
developed heat-exchanging surface heat engineering efficiency is spesified and the analysis of this impact changing reasons
is given.
Key words: fouling, heat-transfer
coefficient, charge air cooler, heat-exchanging surface, thermal resistance.
