Analysis of the Flow Parameters of Gases Across Closed Pipe ection using Principal Component Analysis

Fluid flow through pipes are characterised by the pressure, temperature, geometric constrictions and the regulatory devices set across its path. The study in this paper concentrates on the data obtained when the pressurised nitrogen gas is made to pass through a control valve to achieve the set pressure at the downstream. The data contains numerous data of pressure, temperature and the PID feedback values at different points along its path. The principal components involved in reaching the set pressure need to be taken for consideration for any future analysis. Hence Principal Component Analysis (PCA) is employed to find the variables with considerable variance. It was observed that the temperature at the inner surface and outer surface at the exit were the principal components.
