Simulation of Single and Twin Impinging Jets in Cross-flow of VTOL Aircrafts (Review)

Abstract

o review published literature on the use of technology and how it has improved autistic children life style. A systematic review of the English literature was performed using the PRISMA guideline. Papers indexed in WOS and Scopus databases were included, adjusted to a timeline between 2016 and 2020 and focused on mobile technology, interventions, improvement of social behavior and communication and autism, aimed to describe the most used mechanism to improve autistic life style. Thirty two (32) papers were included in the review. We obtained 14 papers on the Scopus database and 18 on the WOS database. The majority of studies evidenced the use of virtual reality, mobile devices, video modelling and robots as the most common applications for autism therapies. Technology has caused an improvement in autistic children life quality. The development of mobile applications, virtual reality applications and robots have showed a positive impact reflected in the performance of daily activities and a better understanding of how they feel, how to behave, how to express themselves and interact with others. Technology gives the opportunity to monitor children status; and offers adaptability, safety, and accuracy of the information.

“…The flow phenomena involved with impinging jets are also important in the context of vertical take-off and landing (VTOL) aircraft and helicopters. In this regard, the study of jet impingement is particularly relevant for assessing the impact that near-ground operations of such aircraft have on the surrounding environment (Wu et al 2016;Cárdenas et al 2020). Impinging jets play also a significant role in geophysical phenomena such as the scouring due to liquid streams impacting on a solid bed (Dong et al 2020).…”
