Hamilton Harbor
.
In this project, EXTRAQT was asked by Eastpoint Engineering, a Canadian engineering firm, to prepare a Digital Twin of Hamilton Harbor. Near this bay, in the western corner of Lake Ontario, a potential aquathermal project was being evaluated. Since sensor data of water temperature is only available in summer (due to ice formation) and the measurements showed anomalous behavior, EXTRAQT was used to simulate this body of water in detail.

Water bodies with depths greater than 5m typically exhibit stratification behavior, which means that water temperature at great depths follows the outside temperature and other environmental conditions with considerable delay. In addition, warmed-up water gets the chance to rise to the surface due to density differences, while cooled-down water settles to the bottom. This causes a temperature variation over the depth of the water body, which requires detailed simulation techniques to accurately describe this behavior in the absence of sensor data. EXTRAQT calculated summer water temperatures in Hamilton Harbor to an accuracy of 1°C and was thus also able to predict winter season water temperatures, both scenarios with and without heat exchangers on the bottom. By these insights, the local temperature impact could then also be determined, associated with the thermal efficiency of the system and the (delayed) correlation between water and air temperatures.
