The deposition of micron sized lubricant oil droplets similar to oil droplets in blow-by gases of Internal combustion (IC) engines on ahot flat plate was studied using a round impinging jet configuration. Five parameters which simulate the different operational conditionsin IC engines were chosen: The impaction nozzle’s outlet diameter, additional air flow rate, plate angle, plate temperature, and nozzle tothe plate distance. An Experimental test-rig was constructed to acquire deposit weight with different parameter values. To find the conditionsof minimum deposition, the deposit’s weight was optimized using the Taguchi design of experiment method with respect to thedesign parameters. Using the experimental data, the predicted optimal value of the deposit weight was confirmed. Analysis of varianceshowed that plate angle is the most influential factor in deposition of fine oil droplets. Scanning electron microscopy (SEM) was used toinvestigate the mechanism of deposition.
