Compared with the original design plan of cooling fan, driving power of the fan after optimizing has dropped form 3. 451kW to 3. 093kW, dropped by 10. 37%, the total efficiency of it has risen form 28.6% to 31.9%, and the re-set target has been reached.
Results showed that the fast drying speed was got by drying seeds with silica gel plus a fan rotating, the ratio of seeds to silica gel (weight to weight) was 1: 10 Seed viability was not influenced by different drying methods.
By the basic principle of modal analysis and CRAS system, experiments and analysis are made on a fan blade， giving first 12 order vibration modes and their respective natural frequencies．This paper provides the foundation and direc-tion of noise reduction and shock absorption of the fan blade.
The results in this paper improve the results obtained by Ding, Chen and Fan in 2002.
In this paper, another form of KKM type theorem on generalized convex spaces is obtained and the problems of von Neumann-Fan type sup inf sup inequalities and variational inequalities are discussed for their applications.
They enzymes included unique (Fan I, Aca I, and Sse 91) and very rare (Bsi I, and Cci N I) species not typical of aquatic ecosystems.
The results are applied to the fan model of a filter, for which an equation aimed at determination of Brinkman's constant is derived within the framework of a self-consistent theory.
The drag force of a cylinder for this model is close to that for the fan model filter.
