Abstract

Cavitation in various nozzles of different geometries and dimensions, i.e., two-dimensional (2D) and cylindrical nozzles, and liquid jets discharged from the nozzles are visualized using a digital camera, and the index for estimating cavitation in a nozzle is discussed. Simultaneous high-speed visualization of cavitation in the cylindrical nozzle and a liquid jet are also carried out to investigate the relation between cavitation and ligament formation. As a result, the following conclusions are obtained: (1) Flow pattern transition in cavitating flows induces the transition in liquid jet patterns. As the liquid flow rate increases, flow patterns of cavitating flows and liquid jets transit from (no cavitation and wavy jet), (developing cavitation and wavy jet), (supercavitation and spray), to (hydraulic flip and flipping jet); (2) When the trace of a cavitation cloud comes out of the nozzle, a ligament is formed at the liquid jet interface. (3) The collapse of cavitation clouds near the exit and induces ligament formation, which, in turn, causes liquid jet atomization; (4) The causal relationship between cavitation cloud and ligament formation holds not only in the two-dimensional nozzle but also in the cylindrical nozzle

Abstract

Live shopping, online reviews, price perception and shipping discounts are features released by the e-commerce platform Shopee. This feature aims to attract consumer buying interest. Ease of shopping will be one of the buying interests of consumers, especially Muslim consumers in Pekalongan district. This research aims to test the influence of Live shopping, online reviews, price perceptions and postage discounts on Muslim consumers' buying interest in the Shopee application, especially in Pekalongan Regency.This research is a type of quantitative research. The data collection method in this research is the questionnaire method using a sample of 96 respondents. The sampling technique uses the Accidental sampling method. This research uses multiple linear regression test data analysis with the help of SPSS 24.0. The research results show that live shopping, online reviews, price perceptions and postage discounts have a positive effect on Muslim consumers' buying interest in the Shopee application. Then simultaneously Live shopping, online reviews, price perceptions and postage discounts also influence Muslim consumers' buying interest in the Shopee application.
