چکیده
A low specific speed centrifugal compressor with leading/trailing edge combined sweep blades is proposed. The performance and internal flow field characteristics are analyzed in detail by numerical simulations, a bench test carried out. It shown that using the swept blade, stage pressure ratio of improved under all operating conditions, maximum increase can reach 6.5%. efficiency be markedly at high rates. Additionally, leading tip leakage reduced separation on blade surface inhibited, loss low-energy masses downstream passage improved. Meanwhile, work area enhance capacity position.
