Modeling and Cleaning Performance Optimization of Conical
Intake quality is crucial to gas turbines’ operation. The cartridge filter in the gas turbine intake system filters the gas and outputs a highly clean gas into the gas turbine, while pulse cleaning technology ensures the continuous and efficient operation of cartridge filters. While the current cylindrical pleated filter cartridge used in pulse cleaning usually At the tube wall, scalable wall function treatment is specified. Turbulence intensity of 5% and turbulent viscosity ratio of 10 were specified at the inlet. The under relaxation factors considered were 0.3 for pressure, 1 for density, 1 for body forces, 0.7 for momentum, 0.8 for turbulent kinetic energy, 0.8 for turbulent dissipation rate, and 1 for Numerical study on pressure drop characteristics for turbulent

Design for back lobe improvement of spiral antenna with conical wall
This paper presents design for back lobe suppression of multiband spiral antenna with conical wall. Elliptically bended edge, rolled-up edge and elliptical dual edge to reduce back lobe were considered. The axial ratio of spiral antenna with a newly designed conical wall edge structure was not almost changed to compare with conventional Abstract. The fundamentals for the stress analysis of conical shells by use of the classical small-deflection theory have been presented in various texts, but before the development of the high-speed computing machines it was not feasible to present the anaylsis in a convenient and usable form.
