PREDICTION IN OFF-DESIGN OPERATION FOR THE HELICAL HEAT RECOVERY EXCHANGER

For pressures over 1,000 psig, special closures should be considered, such as inte- gral construction (no flanges), welded diaphragm seals, or breech lock closures. Welded diaphragm and breech lock closures are discussed in Section 533.

The correct determination of protein–protein interaction interfaces is important for understanding disease mechanisms and for rational drug design. To date, several computational methods for the prediction of protein interfaces have been developed, but the interface prediction problem is still not f[r]

Heat exchangers are a device that exchange the heat between two fluids of different
temperatures that are separated by a solid wall. The temperature gradient, or the differences in
temperature facilitate this transfer of heat. Transfer of heat happens by three principle means:
