This present work looked at the effect of sand blocking
the heat transfer area of the radiator and its
effect on the engine coolant through the conduct of
experiments and a mathematical model developed.
The results indicated that the percentage area covered
resulted in a proportional increase of the inlet
and outlet temperatures of the coolant in the radiator.
The mathematically model developed also predicted
the experimental data very well. Regression
analysis pointed out that every 10% increase area
of the radiator covered with silt soil resulted in an
increase of about 1.7oC of the outlet temperature of
the radiator coolant. Similarly, using mud as a cover
material, 10% of the area covered of the radiator
resulted in an increase of about 2oC of the outlet
temperature of the radiator coolant. Statistical
analysis pointed to the fact that the result obtained
for mud, silt and the mathematical model were not
significantly different. Thus, irrespective of the type
of material that blocks the radiator surface area, the
coolant rises proportional of the radiator covered. |
