Lip separation is one of the primary sources of inlet distortion, which can result in a loss in fan stability. High angles of incidence are one of several critical causes of lip separation. There have been many studies into inlet performance at high incidence, including the resulting distortion levels when lip separation occurs. However, the vast majority of these investigations have been carried out experimentally, with little in the way of computational results for inlet performance at high incidence. The flow topology within an inlet when lip separation has occurred is also not well understood. This work aims to demonstrate a suitable model for the prediction of inlet flows at high incidence using ANSYS CFX, looking at both the performance of the inlet and the separated flow topology within the inlet. The attenuating effect of the fan is also investigated, with particular emphasis on the flow redistribution ahead of the fan. The results show that the model used is suitable for predicting inlet performance in adverse operating conditions, showing good agreement with experimental results. In addition, the attenuation of the distortion by the fan is also captured by the numerical model.

We present here our findings from the qualitative study commissioned by the Scottish Government (Justice Analytical Services) to provide an understanding of the nature of sectarianism in a range of communities across Scotland, including those where it may be most visibly prevalent. The team of academics commissioned to carry out this research were drawn from the disciplines of law, music, social geography, cultural studies, and communication and media studies. The study was commissioned on 14 March 2014, to conclude in spring 2015.
