Design of spiral turbine for 500W application / Siti Faizah Osman_
Projek ini membentangkan reka bentuk turbin lingkaran untuk penjanaan tenaga elektrik. Penyelidikan ini menerangkan kerja-kerja reka bentuk sistem dan keputusan applikasi ujian turbin lingkaran. Bentuk lengkung digunakan untuk reka bentuk bilah dan ciri-ciri aerodinamik membolehkan turbin untuk bukan sahaja menjadi serba boleh dalam penggunaan, tetapi juga jauh lebih efisien dalam penghasilan tenaga elektrik untuk tujuan yang berbeza. Kebolehan turbin lingkaran bilah telah dijalankan dengan menggunakan simulasi berangka dalam perisian ANSYS CFX. Turbin lingkaran dibina dengan menggunakan perisian SolidWorks dan diuji pada keadaan yang berbeza halaju air yang masuk dan saiz dinding domain yang statik untuk memberi maklumat terperinci tentang ciri-ciri turbin. Formula reka bentuk untuk bilah itu diperoleh dengan menggunakan pelbagai faktor berdasarkan undang-undang pemuliharaan momentum sudut. Ciri-ciri aerodinamik termasuk kuasa keluaran, pekali kuasa dan kesan sudut serang disiasat dengan menggunakan pengiraan simulasi dinamik bendalir (CFD). Interaksi antara aliran bangun di pemutar hiliran dan halaju yang disebabkan oleh vorteks hujung telah dipengaruhi oleh kelajuan air dan kelajuan putaran bilah. Simulasi CFD menunjukkan bahawa turbin hidro ini menghasilkan kuasa yang agak tinggi iaitu 500W dalam keadaan kelajuan air dan kelajuan putaran bilah yang rendah. Kebolehan turbin hidro lingkaran telah diuji dan keputusan penuh dinyatakan. _______________________________________________________________________________________________________ This project presents the design of the spiral turbine for the electricity generation. This research paper describes the design work of the system and the applicability of the spiral turbine test results. The use of a curve pattern for blade design and an aerodynamic characteristic allows the turbine to be versatile in its uses, but also much more efficient at gathering forms of energy for different purposes. Spiral turbine performance of the blade was carried out by using numerical simulation in ANSYS CFX software. The spiral turbine is built by using SolidWorks software and tested for different configuration of inlet velocity of water and size of wall of stationary domain to provide detailed information about the turbine characteristics. The design formula for the blade was derived by using a variety shape of factors based on the angular momentum conservation law. The aerodynamic characteristics including output power, power coefficient and effect of the angle of attack was investigated by using computational fluid dynamics (CFD) simulations. The interaction between the wake flow at the rotor downstream and the induced velocity due to the tip vortices were strongly affected by the velocity of the water and rotational speed of the blade. The CFD simulations showed that the new type of hydro turbine produced a power that is relatively high which is 500W in a lower inlet velocity of water and rotational speed of the blade. The performance of the designed spiral hydro turbine was examined.
