There are two major aspects treated in this paper. The first concerns the management of potato crop for minimizing the impact to environment and people. Organic potato and its technology are the key words for such management. The second aspect adresses the post-harvest management of organic potato obtained in a friendly environment system, aiming the preservation of their initially quality properties. For this purpose a method for testing using a digital potato is presented. The digital potato is a high tech measurement device, very useful for testing the impact between mechanized system and soil as well as the impacts between potatoes and harmful surfaces from the handling chain. The results obtained with this device are important in the harvest and postharvest potato management for obtaining quality potato for people consumption.
In this paper fourteen different CFD cases for CFH (cylindrical film hole) and LDIFF (film hole with laterally diffused exit) geometries were conducted to study the film cooling of flat plates. Those cases included different blowing ratios: 0.5, 1.25 and 1.5 and both steady flow and pulsed jets. In the jet pulsation cases the Duty Cycle was taken 50% and the Strouhal number ranged from 0.0119 to 1.0 for the CFH geometry and from 0.0119 to 0.38 for the LDIFF geometry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
