Dynamic Modelling of Natural Draft Cooling Tower (Case Study of Notore Chemical Company)

Abstract

Determining the impact of air, water, and temperature flow rates on the cooling tower of Notore Chemical Industries is the aim of this study. Using a dynamic and simulation model derived from fundamental ideas, this study produced a model equation for an ordinary differential equation. The Runge-Kulta ODE45 technique, which was implemented in MATLAB R2022A, was then used to solve the model equation.The twenty-four-hour simulation runs at one-hour intervals. To ascertain how modifications to the cooling tower's input parameters may affect its output parameters, sensitivity analysis was conducted. As a consequence of increasing the air mass flow rate at 500 kg/hr intervals, the cooling efficiency, cooling range, and cooling capacity will all improve proportionately, from 0.90 to 0.98. On the other hand, when the mass flow rate of water was increased at intervals of 100 kg/hr, the cooling tower's efficiency decreased from 0.90 to 0.60 in terms of capacity and range. The study concludes that increasing the fill arrangement, tower height, and air flow rate has a good effect on the cooling tower. Since the results support the objectives and aims of the study, they are reliable, sound, and appropriate for use..
