Using the HM 162.39 accessory, the user can simulate a very rough flume bed in the HM 162 Modular Flow Channel. The flow bed is made of stainless steel to which pyramid-shaped epoxy resin bodies are bonded. These bodies absorb flow energy from the water. Inlet and outlet panels are fitted at the ends. Removable carrying handles are used to transport the unit to the place of use; the bed is bolted to the base of the channel.
Learning Objectives / Experiments
Experiments on the following topics are possible: - Effects of rough beds on flow behaviour - Effects of the absorption of energy on the water flow rate in open
Using further accessories, investigations in the offshore area are also possible. Thus, e.g., the effects of a rough bed on wave breaking behaviour can be investigated with the wave generator HM 162.41.
