	1	Interaction tonal noise generated by contra-rotating open rotors显示文摘Fast and accurate prediction of sound radiation of Contra-Rotating Open Rotors(CRORs)is an essential element of design methods of low-noise open rotor propulsion systems.In the present work,a previous frequency-domain model is extended to predict CROR noise.It builds explicitly the relationship between harmonic loadings and corresponding tonal noise,by which the influential parameters to noise generation can be clearly understood.The real distribu-tions of steady and unsteady blade loadings are calculated by the Nonlinear Harmonic(NLH)method.In the present hybrid approach,both the CFD and acoustic modules are solved in the fre-quency domain.To assess the accuracy of the developed method,the loading noise of a CROR is calculated and compared against results by using the time-domain FW-H module of NUMECA.The predicted sound directivities by the two methods are in good agreements.The present acoustic model in the frequency domain is proven to be accurate and have high efficiency in far-field noise prediction and data processing.Furthermore,the characteristics of the CROR interaction tonal noise are analyzed and discussed.

	2	Biomimetic Alveolus-on-a-Chip for SARS-CoV-2 Infection Recapitulation显示文摘SARS-CoV-2 has caused asevere pneumoniapandemic worldwide with high morbidity and mortality.Howto developa preclinical model for recapitulating SARS-CoV-2 pathogenesis is stil urgent and essential for the control of the pandemic.Here,we have established a 3D biomimetic alveolus-on-a-chip with mechanical strain and extracellular matrix taken into consideration.We have validated that the alveolus-on-a-chip is capable of recapitulating key physiological characteristics of human alveolar units,which lays a fundamental basis for viral infection studies at the organ level.Using virus-analogous chemicals and pseudovirus,we have explored virus pathogenesis and blocking ability of antibodies during viral infection.This work provides a favorable platform for SARS-Cov-2-related researches and has a great potential for physiology and pathophysiology studies of the human lung at the organ level in vitro.
