Most studies of mass transfer rates, which directly affect reaction rates and yield, have been done on a volume-averaged basis, although some measurements of bubble size and bubble surface area have been done to

Marlies Geier do we find this high percentage of ‘foreign’ control in fluid power, when fluid power itself is quite capable of controlling its own power circuits? The main reason for this phenomenon is the lack of education in the fluid power field itself. For many years electrical control was considered to be ‘

The study of the forces and stresses of the sealing contact has always been one of the basic steps in the process of designing a seal. In this paper the problem is treated by applying up-to-date finite element methods in combination with more traditional analytic techniques. In the experimental part

However, once the Reynolds number exceeds a certain threshold level, a process of amplification of small disturbances in the flow field causes the boundary layer near th
