Abstract

Pipes are used as a means of fluid transportation from a reservoir to a destination. In a piping system, flow loss or head loss is always found, both head loss due to pipe size and head loss due to bends, one of which is the knee. The purpose of this study was to determine the effect of knee diameter on flow headloss. The method used is simulation and monogram calculation. Based on the standard ASME B16.9 B16.28 used knees with a diameter of 1, 2, 4 and inch. The experimental results show the same behavior between the simulation and the monogram calculation. The larger the knee diameter, the smaller the head loss. Headloss simulation results for knee diameters 1,2,4 and 6 inches are 0,012 m, 0,0093 m, 0,00063 m and 0,00426 m, respectively. Meanwhile, the headloss calculated by the monogram is 0.006 m, 0.0024 m, 0.0007 m and 0.004 m, respectively. The smallest headloss occurred at 4 inches in diameter indicating that the knee with this diameter is the best knee among the other four knees

Abstract

The goal of this research was to find out the aerodynamic body design of Mataram Proto. Using Solidwork 2015 for modeling the body and Ansys 2015 for numerical simulation were the main tools of this research. The body was drawn with scale 1: 1 and then imported into Ansys 2015 for meshing. The unstructured meshes were used in this research. After those, using Ansys 2015, the numerical simulation was conducted with viscous model k - e with realizable type. The result of this research was the average drag coefficient of the original Mataram Proto body was 0,17 and its average lift coefficient was 0.17. For the modification Mataram Proto body, the average drag coefficient was 0.06 and 0.13 for average lift coefficient. These proved that the modification Mataran Proto body was more aerodynamic.
