Problem #3. Exploring mosfet via simulation . By adding a diode the inductor current has a path to flow through when the mosfet is OFF. Under normal conditions the diode is OFF. Since this is a discrete mosfet there is no wafer/substrate where you can connect the body terminal. Therefore the body is connected to the source because the

flow takes place due to a head difference of hL across the specimen and the flow is upwards through the specimen. In Fig. 7.8 c the flow through the specimen is downwards again due to a head difference of hL. When there is flow the hydraulic gradient i is given by hL/L. For all three situations the total vertical stress is the same.

Figure 12 presents energy production rates and their evolution over time for three flow rates 6 12 and 24 L/s . It is found that the lowest flow rate has the most stable energy production rate. On the other hand the largest flow rate results in a higher production rate at the initial injection period which later decreases slowly.
