Introduction
Chris (JC) Kloppers PhD, owner and developer of WetCooling Software, is a mechanical engineer who has made significant contributions to the field of wet-cooling tower design and performance prediction. His doctoral thesis, "A Critical Evaluation and Refinement of the Performance Prediction of Wet-Cooling Towers," was published in 2003 and is considered a seminal work in the field.
Kloppers' research has focused on developing more accurate and reliable methods for predicting the thermal performance of wet-cooling towers. He has also investigated the influence of temperature and humidity inversions on cooling tower performance. His work has been widely cited and has had a significant impact on the design and operation of cooling towers around the world.
In addition to his research contributions, Kloppers has also been involved in the development of commercial cooling tower software packages. He is a respected expert in the field of cooling towers and is frequently consulted by industry and government organizations.
Here are some of Kloppers' key contributions to the field of cooling towers:
- Developed a new extended empirical relation for the loss coefficient of fills, which accounts for viscous and form drag effects as well as buoyancy, momentum, and fill height effects.
- Extended the empirical equation for the transfer characteristic of fills to include the effects of fill height and inlet water temperature.
- Developed empirical equations to predict the temperature inversion profile, height of the temperature inversion, and the height from which air is drawn into the cooling tower.
- Investigated the influence of temperature and humidity inversions on the performance of wet-cooling towers.
- Developed a comprehensive analytical computer program to predict and optimize the performance of wet-cooling towers.
- Developed computer programs to generate cooling tower performance curves, analyze fill performance test data, and plot psychrometric charts.
Kloppers' work has had a significant impact on the design and operation of cooling towers around the world. His contributions have made cooling towers more efficient and reliable, and have helped to reduce the environmental impact of industrial processes.
