• Theoretical and Experimental Investigation of the Dynamic Behaviour of Centrifugal Fans

  In this paper, a theoretical model is proposed to investigate the centrifugal fans' transient behaviour in response to sudden imposed changes in pressure or flow rate. We are especially interested in the dissipative or creative energy transient behaviour of the fans located in actual aeraulic networks.

  The model is based on the global modelisation of the motor and resistant torques (due to pressure and viscosity actions on the blades) which are present on the rotor and by their coupling with its inertia.

  The model is then validated by experimental measurements which show its validity. In the case of the tested fan, the instantaneous characteristics (in particular the flow rate and rotation speed) have been correctly predicted by the model, with regard to time as well as amplitudes, provided the flow is not reversed.

  本文提出了一个理论模型，用于研究离心风机在压力或流量突然变化时的瞬态行为。该模型基于转子上存在的电机和阻力矩（由于叶片上的压力和粘度作用）的全局建模，以及它们与转子惯性的耦合。在测试的风机中，只要流量不逆转，模型就能正确预测瞬时特性（尤其是流速和转速）的时间和振幅。

  hydride in MeCN followed by treatment with alkylating reagents. The developed alkylation method was applied to the preparation of hardly available 2-alkylsemicarbazides and their hydrochlorides from semicarbazide hydrochloride. This general and efficient protocol is based on preparation of acetone semicarbazone, its alkylation, and hydrolysis under mild conditions.

• Synthesis of 2-Amino-1,3,4-oxadiazoles and 2-Amino-1,3,4-thiadiazoles via Sequential Condensation and I₂-Mediated Oxidative C–O/C–S Bond Formation

  2-Amino-substituted 1,3,4-oxadiazoles and 1,3,4-thiadiazoles were synthesized via condensation of semicarbazide/thiosemicarbazide and the corresponding aldehydes followed by I-2-mediated oxidative C-O/C-S bond formation. This transition-metal-free sequential synthesis process is compatible with aromatic, aliphatic, and cinnamic aldehydes, providing facile access to a variety of diazole derivatives bearing a 2-amino substituent in an efficient and scalable fashion.
