Abstract:
Thermo-hydraulic flow situations in short narrow channels are studied.
Nu-
merically obtained results are compared with experimental ones.
Nusselt
number correlations are developed for velocity and temperature non-developed
profiles.
Results for heat transfer coefficients are used as boundary condi-
tions for temperature distribution computations in an oil-air cooling engine
cylinder.
Introduction
Owing to the vicinity of the exhaust channel, shape of the engine cylinder
cooling surfaces, there is a pronounced asymmetric circumferential tem-
perature distribution in the cylinder wall.
This temperature ovalty can be
minimized by controled intensity of the local cooling.
A curved square cross
section channel supplied with lubrication engine oil was introd...
