One of the main ideas in the project is to control the flow induced by a bacterial carpet in a micro-tube. This is done by changing the tumble frequency of the bacteria when they are exposed to light. It is however not clear what the exact connection between the tumble frequency and the overall liquid flow is. This matter is complicated by the fact that the bacterial pump it self is a selforganizing system and changing the tumbling of the bacterial could therefore change the structure of the overall system completely. One way to assess this connection between tumble frequency and the flow is to create a physical model, that describes the most essential features of the system. Our work connected to the development of such a model is presented in the following. The basis for any model is a understanding of the physical system in question, there will we start with a short review of the hydrodynamic properties of flagella and the bacterial pumping system constructed by[artikel reference].
