Lee, B.H.K. (author), Westley, R. (author)Using experimental measurements of the sound pressure and phase in the near field of a choked screech jet, a method is proposed for computing the effective source positions, their strengths and phases. Two models are considered. The first assumes a distribution of point sourees along the jet axis and the second assumes ring sources along the jet...report 1971

Lee, B.H.K. (author)A theoretieal treatment of plane progressive sound waves of finite amplitude in a non-dissipative medium produced by a piston whose motion contains many different frequeney components is presented herein. The solution of the seeond-order wave equation is represented in the form of a Fourier series and the eoeffieients are expressed in terms of...report 1971

Lee, B.H.K. (author)The blast wave equations in an unsteady environment are derived. For wedge and conical nozzles it is shown th at the density has a power law vari ation with distance downstream from the throat when the loeal flow Mach number is large. The unsteady flow field behind the blast wave is solved by a perturbation technique and the sel f-similar...report 1968

Lee, W.A. (author)The glass temperature (TG) of polymers is defined and methods for its determination are enumerated. The influence of rate of measurement, purity and condition of sample on observed TG' s and the interpretation of data and criteria for their assessment are discussed. TG's of 424 homopolymers are tabulated with a comprehensive bibliography of 353...report 1965

Lee, W.A. (author)Factors governing the glass transition temperature, (Tg), of a polymer, namely, chemical composition, side-chain structure, cross-linking, stereoregularity, shape, molecular weight, crystallinity, diluents, and copolymerisation are qualitatively and briefly described. The effect of temperature on physical properties near the Tg and the...report 1964

Lee, P. (author)Tests have been made in the 8' x 6' ' Transonic Tunnel to determine the aerodynamic characteristics of the Hindustan Aircraft Ltd. H.J.T-16 over the possible flight ranges of incidence, sideslip, and Mach number. Various configurations were tested to investigate the aircrafts longitudinal and directional stabilities, elevator, tailplane and...report 1963
