Abstract

The Knudsen pump (KP) is a type of micropump that may produce thermally induced flows in rarefied gas environments. These flows are caused by temperature fields in the environment. It offers the benefits of having no moving components, having a basic structure, being easy to construct and extend, having access to a wide variety of energy sources, and having a low overall energy usage. This project focuses on designing hot chamber with heating element. As the heating element being heated, it will produce hot gas within the chamber. Thus, the gas flow as well as the temperature difference can be analyzed. As the heating element is used to heat up the chamber, a thermocouple which functions as sensor that is used to measure the temperature as it is placed inside the hot chamber. After the temperature rises to desired value, the gas flow is then can be analyzed and observed. The observation is made by witnessing the hot gas flow transferred from the hot chamber to a narrow channel which then transferred to cold chamber. The comparison of temperature difference can be compared by the data observed.
