Experimental data are presented for large arrays of rotating, variable-height cylinders in order to study the dependence of the three-dimensional mean flows on the height heterogeneity of the array. Elements in the examined arrays were spatially arranged in the same staggered paired configuration, and the heights of each element pair varied up to 637.5% from the mean height (kept constant acros...

Different types of permanent magnet generators for wind power application have been subject of research during last two decades. In this thesis different topologies of electrical generators have been investigated for small scale vertical axis wind turbine application. A two stage induction generator is proposed as a alternative solution with respect to the cost of such a system. However, a bigg...

This paper presents the influence of strut and tower on aerodynamic force blade for vertical axis wind turbine (VAWT). It has been known that struts degrade performance VAWTs due to inherent drag losses. In this study, three-dimensional Reynolds-averaged Navier–Stokes simulations have conducted investigate effect flow pattern around rotor region, distribution, performance. A comparison made thr...

in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...

biological fertilizers can be suitable alternative to chemical fertilizers to increase soil fertility and crop production in sustainable agriculture. in order to evaluation of integrated application of bio-fertilizers and chemical fertilizers on on quantitative and qualitative yield of ajowan in strip intercropping, a field experiment was conducted in a factorial design based on randomized comp...
