Pensimulasi ECT ialah satu alat yang boleh menjana data ECT untuk pelbagai corak aliran gas-cecair berdasarkan dimensi penderia ECT yang ditakrifkan. Dengan menggunakan pensimulasi ECT, ukuran kapasitan boleh dijana berulang kali tanpa sistem penderia yang sebenar. Ia membantu dalam kegiatan ujikaji makmal dan dalam bidang penyelidikan terutamanya untuk pembinaan semula imej Tomografi Kemuatan Elektrik. Terdapat beberapa pensimulasi ECT tetapi harga yang mahal menjadi faktor penghalang. Pensimulasi ECT yang digunakan dalam penyelidikan di Pusat Pengajian Elektrik & Elektronik, Universiti Sains Malaysia (USM) adalah berdasarkan sebuah pensimulasi yang telah dibangunkan di University of Leeds, United Kingdom. Bagaimanapun , ia tidak mesra pengguna kerana input yang diterima adalah di dalam bentuk Decomposed Geometry Matrix (DGM). Bagi menghasilkan DGM, pengguna mesti terlebih dahulu mengira bagi mengenal pasti koordinat-koordinat yang terlibat bagi setiap corak aliran. Pengiraan yang mesti dilakukan boleh menyebabkan kesilapan dan ia juga memakan masa. Oleh itu, projek ini bertujuan membina sistem yang dapat menerima lukisan corak aliran dua komponen daripada pengguna sebagai antaramuka pensimulasi ECT. Sistem ini juga boleh mengira pecahan kandungan gas bagi lukisan corak aliran dua komponen daripada pengguna. Selain itu, pengguna boleh mengubah saiz sudut elektrod primer dan elektrod adang bagi penderia ECT untuk mengubah kepekaan pensimulasi ECT. Sistem ini adalah lebih mesra pengguna dan ia dibina menggunakan MATLAB. Bagi memastikan ketepatan sistem yang dibina, bacaan-bacaan ECT yang dihasilkan oleh sistem dibandingkan dengan yang terhasil daripada DGM. Keputusan perbandingan mengesahkan kejayaan pembinaan sistem ini. ___________________________________________________________________________________ ECT simulator is a tool which can generate ECT data (capacitance measurements) for different flow patterns of all investigated flow regimes based on the defined dimensions of the ECT sensor parameters. By using ECT simulator, the capacitance measurement can be generated repeatedly without the need of the actual ECT sensor. It helps in the laboratory experiment activities and researches particularly in the field of Electrical Capacitance Tomography image reconstruction. There are ECT simulators exist but they are expensive. The one that is used by researchers in the School of Electrical & Electronic Engineering, Universiti Sains Malaysia (USM) is based on a simulator developed at the University of Leeds, United Kingdom. However, it is not user friendly because the inputs must be in the form of Decomposed Geometry Matrix (DGM). In order to generate DGM, users must carry out calculation to determine the coordinates involved for each flow pattern. This may cause errors in calculation and is also time consuming. Hence, the main purpose of this project is to build a system which can accept the flow pattern drawn by user as the input for the ECT simulator. This system is also capable of calculating the void fraction of a drawn flow pattern. Besides that, this system allows users to change the primary electrode and guard electrode angular sizes of the ECT sensor to adjust the sensitivity of the ECT simulator. This system is more user friendly and built using MATLAB. In order to verify the correctness of this system, the ECT measurements generated by the system are compared with the ECT measurements generated based on the obtained DGM. The comparison results prove that this tool kit has been successfully built.
