Finite Element Modeling of Compressor Discharge Tubes

Discharge tubes in hermetically sealed refrigeration compressors are often a source of fatigue failure which is not serviceable and necessitates the replacement of the compressor. The finite element method can be used to model the discharge tube to help prevent such failures and to reduce costs by optimizing the tube. This investigation considers techniques for modeling discharge tubes with fin...

River Discharge Time Series Prediction by Chaos Theory

The application of chaos theory in hydrology has been gaining considerable interest in recent years.Based on the chaos theory, the random seemingly series can be attributed to deterministic rules. Thedynamic structures of the seemingly complex processes, such as river flow variations, might be betterunderstood using nonlinear deterministic chaotic models than the stochastic ones. In this paper,...

Stresses In Reciprocating Compressor Discharge Tubes During Starting

A numerical method is presented for computing the time varying stresses in reciprocating compressor discharge tubes during starting. The tube is described using shell elements, and mounting springs are described using beam elements. Mass and stiffness matrices are assembled into a second order system of equations that is then solved in a time step fashion along with mechanism and induction moto...

The Synthesis of Carbon Nano Tubes by Arc Discharge Method in Liquid media

In this investigation a simplified arc discharge apparatus was used to synthesize mullti-wall carbon nanotubes. Because of not requiring vacuum equipment, heat exchange system, active or inert gases, this method is found to be cheaper and simpler than traditional arc discharge in gas environment. Using this method, CNTs are produced by performing an arc discharge between two graphite electrodes...
