  2. 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

  3. 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

  4. 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

  5. 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

  6. Next Steps • Finish the heat and mass transfer algorithm • Model the six cases in FLOW3D • Analyze and compare the analytical and numerical results
