“…The results showed that the drag coefficient of Makhobeli, triticale and wheat seeds decreased as moisture content increased. Afonso et al (2007), Gupta et al (2007) and Irtwange and Ugbeka (2003) reported similar results for coffee cherries, sunflower seed and African yam bean (cv. TSS 138), respectively.…”

“…The major dimensions of the seeds (L and W) were measured using a digital caliper with an accuracy of ± 0.01 mm (Gupta et al, 2007). The true density of the seeds was measured using the toluene displacement method (Chakraverty and Poul, 2001;Unal et al, 2013;Zare et al, 2013).…”

A b s t r a c t. The objective of this study was the evaluation of the aerodynamic properties of Makhobeli, triticale and wheat seeds as a function of moisture content from 7 to 27% (w.b). The results showed that the terminal velocity of triticale and wheat seeds increased linearly from 5.37 to 6.42 and from 6.31 to 8.02 m s -1 , respectively, as the moisture content increased from 7 to 27%. Over this same moisture content range, the terminal velocity of Makhobeli seeds varied following a polynomial relationship from 4.52 to 5.07 m s -1 . Makhobeli seeds had terminal velocities with a mean value of 4.73 m s -1 , at different moisture contents, compared to the mean values of 5.89 and 7.13 m s -1 for triticale and wheat seeds, respectively. The mean value of drag coefficient was 1.12 for Makhobeli compared to the values of 0.92 and 0.85 for triticale and wheat, respectively. The analysis of variance showed that there were significant differences between the terminal velocity (at 1% probability level) and drag coefficient (at 5% probability level) of Makhobeli with triticale and wheat seeds, which suggests that aerodynamic separation of Makhobeli from triticale and wheat is possible.K e y w o r d s: separation, post harvest operation, Makhobeli, weed control, triticale, wheat

“…Drag coefficient is the measure of drag or resistance of an object to moving air or water. The drag force is a function of terminal velocity, fluid density, projected area and drag coefficient (Gupta et al, 2007). The piles of agricultural materials in silos resist the airflow because of their blockage of air way and their surface friction.…”
