...TAMPERE UNIVERSITY OF APPLIED SCIENES Environmental Engineering Final thesis Timo Flaspöhler Design of the runner of a Kaplan turbine for small hydroelectric power plants Supervisor Commissioned by Tampere 2007 Jaakko Mattila Tampere University of Applied Sciences, Mechanical engineering department TAMPERE UNIVERSITY OF APPLIED SCIENES Environmental Engineering Timo Flaspöhler Final thesis Supervisor November 2007 Keywords Design of the runner of a Kaplan turbine for small hydroelectric power plants 78 pages, 42 pages Appendix Jaakko Mattila Electricity tariff, small hydroelectric power plant, Kaplan turbine, runner, adaptation mechanism, stress analysis, technical drawings ABSTRACT The final thesis deals with the design of the runner of a Kaplan turbine. It might be that due to the increasing of the electricity tariff in the last years small hydroelectric power plants become cost effective. Since the runner of a small hydroelectric power plant is quite small, it has to be reexamined if the hub of the runner provides enough room for a proper adaptation mechanism. For this purpose the main characteristics of the runner are determined. Then, important data such as the suction head, the occurring forces or the critical speed are established. After those data are known, a detailed stress analysis of the developed adaptation mechanism follows. The stress analysis shows that the mechanism to adjust the blades is able to withstand the occurring forces. Finally...

...Chaotic Growth with the Logistic Model of P.-F. Verhulst Hugo Pastijn Department of Mathematics, Royal Military Academy B-1000 Brussels, Belgium Hugo.Pastijn@rma.ac.be Summary. Pierre-Fran¸ois Verhulst was born 200 years ago. After a short biograc phy of P.-F. Verhulst in which the link with the Royal Military Academy in Brussels is emphasized, the early history of the so-called “Logistic Model” is described. The relationship with older growth models is discussed, and the motivation of Verhulst to introduce different kinds of limited growth models is presented. The (re-)discovery of the chaotic behaviour of the discrete version of this logistic model in the late previous century is reminded. We conclude by referring to some generalizations of the logistic model, which were used to describe growth and diffusion processes in the context of technological innovation, and for which the author studied the chaotic behaviour by means of a series of computer experiments, performed in the eighties of last century by means of the then emerging “micro-computer” technology. 1 P.-F. Verhulst and the Royal Military Academy in Brussels In the year 1844, at the age of 40, when Pierre-Fran¸ois Verhulst on November c 30 presented his contribution to the “M´moires de l’Acad´mie” of the young e e Belgian nation, a paper which was published the next year in “tome XVIII” with the title: “Recherches math´matiques sur la loi d’accroissement de la e population” (mathematical investigations of the law of...
