Rotor-bearing dynamic research on an E-type gas turbine-generator set
In this paper, every rotor in the shafting of an E-type gas turbine-generator set is simplified for numerical simulation. Finite element analysis on lateral critical speed, unbalance response and stability is carried out systematically. The simplified model and the conclusions would provide a reference for designing another similar type gas turbine-generator set.
Model test and analysis of gas turbine rotor
This paper takes a type gas turbine rotor as an example to analyze its natural frequency and modal shape.The transfer matrix method is also used to compute its model.Analysis and the test results offer clues for further research of the construction and stiffness of gas turbine rotor.
Laminar heat or mass transfer in rectangular channels and in cylindrical tubes for fully developed flow: comparison of solutions obtained for various boundary conditions
Abstract A comparison is made of results obtained with various boundary conditions at the wall of the channels. By comparing blood Sherwood numbers for finite wall resistance with those for constant concentration boundary condition only a small variation is found for various points along the blood channel.
