The rotary engine (RE) is a potential power plant for unmanned aerial vehicles (UAVs) and automobiles because of its structural design merits. However, it has some serious drawbacks, such as frequent maintenance requirements excessive fuel consumption. This review paper presents the current status hydrogen-fueled (HRE) technology identifies existing research development gaps in combustion effic...

Indonesia is an agricultural country with 40% of the population's livelihood provided by farmers. Harvested rice typically has a moisture content 20-27% on wet basis. The type artificial dryer that often used tub or rotary type. This research aims to develop using combined tray and rotary-type method. Based result, higher speed dryer, shorter drying time. net result this test relationship betwe...

Abstract An axial vane rotary engine (AVRE) is a novel type of engines. The positive displacement mechanism that permits the four “stroke” action to occur in one revolution shaft with minimum number moving components comparison reciprocating In this paper, two-zone combustion model developed for spark ignition AVRE. chamber divided into burned and unburned zones differential equations are chang...
