Analysis of Tube Configuration in a Tube Bundle in Horizontal, Two-Pass CondensersEngineering ProjectMaster of Engineering in Mechanical Engineering Jennifer Tansey 10/20/11
Introduction / Background • A common type of condenser used in steam plants is a horizontal, two-pass condenser • Steam enters the condenser through an inlet at the top of the condenser and passes downward over a horizontal tube bundle • The tube bundle is made up of individual tubes through which a cooling medium circulates to condense the steam • Typically the tubes in the top half of the tube bundle are the “cold,” first pass and the tubes in the bottom half are the “warmer,” second pass
Problem Description • The objective of this project is to analyze the tube configuration in a bundle to determine the best arrangement of tubes for the maximum amount of heat transferred to the circulating water • The six configurations shown will be analyzed • The dark blue denotes the first pass tubes and the light blue denotes the second pass tubes
Current Status • Researched previous work performed on two-pass condensers and flow over tubes • Determined the mathematical approach to solve the problem under evaluation • Established the initial conditions and assumptions for the problem (i.e., condenser dimensions, number of tubes, operating conditions including shell-side and circulating water parameters) • Completing the heat and mass transfer algorithm to determine the outlet temperature of the circulating water for the six cases
Current Status • Chose an appropriate RANS software (FLOW3D) to model the condenser • Beginning the numerical analysis by creating the baseline conditions and geometry in FLOW3D
Next Steps • Finish the heat and mass transfer algorithm • Model the six cases in FLOW3D • Analyze and compare the analytical and numerical results
