N2 - A lot of experimental observations in magnetic confinement devices show that the particle and thus heat transport in the scrape-off layer (SOL) of the plasma is characterized or even dominated by turbulent intermittency. This process, characterized by (higher density) blobs which are projected radially outwards onto the wall, increases the wall erosion and reduces the divertor efficiency. In view of ITER and other machines under construction, this interaction of the plasma with the wall is still an important topic. In this contribution, we analyse some simulations with the ESEL (Edge SOL Electrostatic) code [1], applied on the geometry of TEXTOR. Input-parameters for the model were taken from ohmic shots in TEXTOR. We completed and analyzed 2 different parameter scans; the output of the runs is compared to results of the real experiment.
