Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

The use of pillow-plate heat exchangers in process industries has been continuously increasing. Usually, the heating or cooling medium flows through the inner channels of the pillow plates, while the process medium flows through the outer channels. The welding spots have an important influence on the three-dimensional structure of the plates and hence on the heat transfer characteristics of the apparatus. However, the welding spots themselves are largely passive with regard to heat transfer.
In the group of Professor Kenig, at the University of Paderborn, the design types used so far were further developed in order to increase the performance. This pillow-plate heat exchanger can be used for all relevant heat transfer applications in the chemical or process industry. This includes processes with phase change (condensation/evaporation). A typical application area is distillation, where pillow-plate heat exchangers can be used as integrated head condenser or reboiler. Further applications are processes with single-phase media on both sides of the apparatus.
A German patent application is pending, international applications are possible. On behalf of the University of Paderborn PROvendis offers licenses to interested companies.
