Kluyver, A.J. (author), Visser, J. (author)1. A method has been developed for testing the filtration efficiency of some filter materials. For each of the materials investigated — cotton wool, stillite and carbon — a suitable filter has been devised. 2. The filtered air was analyzed as to its germ content with the aid of a set of 3 capillary impingers. 3. The cotton wool filter gave on...journal article 1950

Robinson, A. (author)The field of flow due to a shock wave or expansion wave undergoes a considerable modification in the neighbourhood of a rigid wall. It has been suggested that the resulting propagation of the disturbance upstream is largely due to the fact that the main flow in the boundary layer is subsonic. Simple models were produced by Howarth, and Tsien and...report 1950

Dowlen, E.M. (author)The profile drag-coefficients of a number of low-drag wings with straight trailing edges have been calculated. A comparison is made with other low-drag and conventional sections which indicates an increase in profile drag, for a given transition point position, with rearward movement of the position of maximum velocity and with increase of...report 1950

Mazure, J.P. (author), Van Hoolwerff, G.H. (author)Het rapport gaat in op "Algemeen plan voor de Zuidwestelijke polder", waarin men tot een plan komt om het waterbezwaar op het Ijmeer in natte tijden zoveel nodig door te voeren op het IJsselmeer. Het rapport onderzoekt deze mogelijkheid aan de hand van metingen en enige omvangrijke berekeningen. Er blijkt dat matige stijgingen van het peil van...report 1950

Lewis, S.R. (author)This report extends the work of W.J. Goodey and gives numerical examples of the shear distribution around a frame subjected to a single concentrated radial load for variations in the parameters, such as, frame stiffness, skin thickness, stringer spacing, etc. It also indicates when the beam theory distribution of shear can be used with a...report 1950
