The startup operations of continuous casting sequences of steel in a 4-strand tundish, using three different turbulence inhibitors (TI), were investigated using a 1/3-scale water model in combination with numerical simulations through the volume of fluid model. The two-phase flow water–air is...
FREQUENCY SPRING SYSTEM WITH HYBRID DIRECT SEQUENCE / FREQUENCY-SPRING OPERATION DURING START-UP PHASEIn a radio system that employs frequency hopping (FH), access time delay is reduced, without compromising processing gain, by adding direct-sequence (DS) spreading to the system. This results in ...
