Abstract: The paper presents a construction of a simplified model approximating the actual observed flow pattern. The resulting expressions for frictional pressure drop are found to agree fairly well with ...

Abstract: It is proposed in this work that the transition to slug flow occurs due to Kelvin-Helmholtz instability, which, in this case, is enhanced by the proximity of the upper wall and becomes ...

Abstract: For the study of certain enzymes, Dr. E. R. Stadtman, Chief, Laboratory of Biochemistry at the National Institutes of Health, desired a room where he could conduct many of the standard chemical ...
