Model a cooling tower in EESPRELIMINARY THESIS PRESENTATION
BY: SHIYAS BASHEER
SUPERVISOR: ANTHONY REYNOLDS
Objective Study on Cooling Towers Recent developments Create a mathematical model Implement it on EES (Engineering Equation Solver) Verify the results Create a user interface Study the effect of changing parameters
Motivation/Justification
Reject waste heat Reduce Thermal Pollution Increase the efficiency of a rankine cycle Interested in thermodynamics Like to work in power generation sector
Cooling Tower
Extract heat Reduce temperature Emit to atmosphere
