A forced convection solar drier is designed with evacuated tube collector and a blower. The performance of the designed drier is evaluated by carrying drying experiments at Thanjavur District, Tamilnadu, India with amla. Solar drying of amla is carried at different air velocity flow rates – 4m/s, 4.25m/s and 4.5m/s and is compared with natural sun drying. The temperature of the drying chamber r...

Abstract The advanced challenges from the vannamei shrimp cultivation nowadays keep on pushing fisheries industry improving its productivity, however, with minimum use of water resource and an efficient land. This research aims to discover growth survival rate that is cultivated in a circular tarpaulin pond microbubble aeration system. shows can increase amount dissolved oxygen (DO) within pond...

The need of cooling arrangement for DC motor is very important to reduce the frame size of the motor. It required to select the effective cooling arrangement of the DC motor based on the application, surrounding of the motor installation and power consumption. DC motors are the workhouse variable speed drives in the continuous steel rolling mills for many years. DC motors in the steel rolling m...

Air pollution due to PM2.5 is of public concern in Korea. Ambient PM2.5 can penetrate indoors through the building envelope, affecting the indoor PM2.5 concentrations. Most people stay indoors for approximately 80% of every day, implying that their primary exposure to PM2.5 could be determined by the indoor air. This study aims to investigate the infiltration of ambient PM2.5 through the buildi...

Almond harvest accounts for a significant amount of PM10 emissions in California each harvest season. This paper addresses the reduction of blower passes during the harvest from 3 to 1 as a possible mitigation measure. Ambient total suspended particulate and PM10 sampling was conducted at two orchards during harvest with alternating control and experimental treatments. Onsite meteorological dat...

Through a mechatronic system, the project of linear blower was born from difficulty found by textile industry (which uses cotton as raw material) in keeping their machines and equipment proper working conditions without residue accumulation, causing several problems damaging final product. To avoid this problem, solution used until then manual cleaning process, which demanded qualified labor fo...

This research is an air table device design and laboratory scale experimentation. Air a tool to separate valuable minerals from mineral impurities of tin ore based on differences in specific gravity, shape size using air/wind media. The the starts manufacture as well other main components, including; feed hopper, ventilation tertoron cloth. Then next stage calculation selection driving motor fo...

In this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. Experiments were carried out by planar imaging and particle image velocimetry (PIV) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and ...
