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
