This study was dealt how to solve the problem of analyzing one dimensionalunsteady state heat conduction in semi-infinite rod at constant thermal conductivity.The problem geometry and meshing were made in ANSYS Workbench. Themathematically model was applied on the basis of Fourier’s law. The model wasanalyzed by ANSYS CFX 12.0 solver. The...

Perkembangan material komposit memungkinkan adanya penggabungan beberapa material yang memiliki keunggulan tertentu. Penambahan serat gelas pada komposit dengan bahan penyusun resin phenolyc LP1QEX dan serbuk genteng sokka dengan ukuran butiran tertentu, akan mengakibatkan perubahan pada kekuatan tarik dan ketahanan bakar komposit tersebut....

ABSTRACTThis work experimentally studied the influence of guide vane design to increaseSavonius rotor performance. Guide vane is one of additional device that its function is todirect wind stream onto concave blade and deserves as obstacle of the wind that flowing on toconvex blade. This method increased wind speeds to the rotor, consequently it...

ABSTRACTWith the continuous outstanding development of electronic devices, the powerquality problems have been remarked as a great growing concern, whereas voltagesag and swell problem are the most frequently occurring and detrimental powerquality problems. Therefore, the purpose of this study was to mitigate voltage sag andswell problem with UPQC...

ABSTRACTThe single lap joint (SLJ) along with adhesive bonding is being used widely in engineering industry due to its easy design process as well as continuously increasing demand for lightweight designing structure. However, yet the precise information about the correlation among the different factors of SLJ such as overlap length, surface...

ABSTRAKStruktur bodi kendaraan harus memiliki sifat bending yang baik, ringan, dan tahan api. Komposit hybrid merupakan sebuah material alternatif yang dikembangkan untuk  memenuhi tuntutan tersebut. Penggabungan serat gelas dan serat karbon sebagai penguat dan penggunaan serbuk genteng Sokka dalam matriks bisphenol-A adalah sebuah terobosan...

In this study, the wind speed characteristics and energy potential in the selected location Al-Fattaih-Derna in the eastern part of Libya have been investigated. The wind speed data was measured in 2003 at height of 50 m. The results shows that the annual mean wind speed is 8.21 m/s, Weibull distribution results has been used to accomplish the...
