What Is a Packed Bed Reactor? COMSOL Blog

What Is a Packed Bed Reactor? COMSOL Blog

Aug 15, 2014 When designing a packed bed reactor, the design must include mass transfer (or species transport) in the bed as well as heat transfer and chemical reactions. Understanding and optimizing the heat transfer through packed beds is important in order to decrease the cost of running the equipment.

Silicon Wafer - an overview ScienceDirect Topics

Silicon Wafer - an overview ScienceDirect Topics

Silicon wafers after cutting have sharp edges, and they chip easily. Wafer edge is shaped to remove sharp, brittle edges; rounded edge minimizes risk for slipping, too. Edge shaping operation makes the wafer perfectly round (off-cut wafers are oval shaped after slicing), the diameter is adjusted, and orientation flat(s) or notch is dimensioned or made.
