The grid generation method for the complicated duct with the staggered perforated baffles is studied as a case,and grid independence standard is well analyzed when the same mesh is used in different Re number.

The properties of heat transfer and flow resistance in helical baffled orifice plate supported by tubular heat exchanger are analyzed and the correlation equations for the coefficients of heat transfer and flow resistance in the shell side are presented.

A new type of the shear connector of the flange type perforated corrugated plate was proposed,the push-out tests for the conventional perforated straight steel plate shear connector and the new shear connector were made and the influences of the numbers of perforating holes and the reinforcement threading or not on the bearing capacity of the two kinds of the connectors were investigated.

The gap between the baffle plates and shell was blocked by the sealer,which effectively decreased the short circuit flow in the shell.

Breakage and leakage took place on the baffle plate heat exchangers of Russian-made 300 MW electric generator units in a power plant shortly after the units were put into operation.

Flow friction characteristics of the holed-baffles;

Manufacture of baffle in gas distributor with eccentric sleeve in the column;
