Fluid Flow Analysis of Mikro Gas Turbine using Computational Fluid Dynamics (CFD)
Abstrak

 

The needs of micro-scale power plant for small and middle residential or industry are beginning to increase, especially for continuous power generation in remote area, emergency standby and peak shaving. There are several types of micro-scale power plant commonly used, such as micro-steam turbine, micro-hydro turbine, micro-gas turbine (MGT), etc. Among those micro-scale power plant, MGT has the highest performance. Therefore, it is a promising technology to develop. In MGT, an automotive turbocharger could be used as the gas generator or and the turbine because it has a compact structure, light weight and commercially available.

 

In order to design a micro-gas turbine, it is necessary to find the optimum design of compressors such as the outlet compressor diameter, the combustion chamber and turbine. This paper describes the analysis of fluid flow in a micro-gas turbine that used an automotive turbocharger as the compressor and the turbine of MGT to generate electric power by using Liquefied Petroleum Gas (LPG). Three models with different diameter of compressor outlet were developed and analyzed. The analysis shows that the compressor outlet diameter of 30 mm has a better velocity distribution, higher Mach number and higher turbulent intensity among other models. The combustion chamber and the turbine also analyzed by using Computational Fluid Dynamics (CFD). The combustion chamber analysis indicates that the combustion of C3H8 and the air were mixed perfectly with maximum chamber temperature of 905.56 K. Meanwhile the turbine analysis indicates that the turbine rotated with a speed of 4087.96 m/s.

Optimization Design of Open Circuit Wind Tunnel Suction Type
Abstrak

This study present optimize design of open circuit wind tunnel suction type based on the cross section shape variation, whist the specification of the axial fan is set at the debit of 8.75 m3/s and the diameter of 1.250 m. TEA (Task Episode Accumulation) and Computational Fluid Dynamic (with Ansys 15.0 version) applied in this study to determine the optimum design. The outcome is wind tunnel design variation 6 has the highest performance among others design. Variation 6 has a length of 5.015 m, speed of 15.0 m/s, Reynolds number of 8.1 x 105, turbulence intensity ranging between 10.25-10.75%, and the specimen must be placed in the middle of plane III and plane III in order to form uniformity in flow.

Keywords: Computational Fluid Dynamic, Design, Open Circuit, Wind Tunnel

Polyetheretherketone (PEEK) for making bone implants in maxillofacial reconstruction surgery
Abstrak

Polyetheretherketone (P.EEK) has been used as a bone implant because it has the nature of a biocompatible, strong, non-corrosive, stable and not affected by high temperatures. PEEK is potential for use as an implant material. Applications in maxillofacial reconstruction surgery is very beneficial in terms of time and cost. Modelmaking mandible obtained from data on patients affected by tumor ameloblstoma. The data have been taken by a CT-scan in the form of DICOM (Digital Imaging and Communication in Medicine) is amended by Catya into STL files (stereolithography). STL file is then printed with 3D-printers and Computer Numerical Control (CNC) machines.Printouts based models have been created for the reconstruction implants in maxillofacial surgery.

Keywords: Polyetheretherketone; implants; reconstructive surgery; maxillofacial; mandible.
