The spacing of streaks in unsteady turbulent wall‐bounded flow
(The American Institute of Physics, 1994-07)
The spacing of streaks of low‐speed fluid has been studied experimentally in a wall‐bounded turbulent flow in which sinusoidal unsteadiness was superposed on an otherwise steady mainstream over a range of frequencies. The ...
Low‐temperature conductivity of epitaxial ZnSe in the impurity band regime
(The American Institute of Physics, 1994-11-14)
Low‐temperature conductivity of several samples of ZnSe grown by molecular‐beam epitaxy has been measured. The data indicate that for samples with carrier concentration below or near Nc, metal insulator transition, the ...
Dynamic response of a rotating beam subjected to an accelerating distributed surface force
(Elsevier, 1992-09-08)
A method is given by which the response of a rotating or non-rotating timoshenko beam can be determined, subjected to an accelerating fixed direction distributed surface force. The beam model includes the gyroscopically ...
Dynamic Instability Of Layered Anisotropic Circular Cylindrical Shells, Part I: Theoretical Development
(Elsevier, 1993-04-08)
A theoretical development is presented for the parametric resonance of layered anisotropic circular cylindrical shells. The shell's ends are clamped and subjected to axial loading consisting of a static part and a harmonic ...
Dynamic Instability Of Layered Anisotropic Circular Cylindrical Shells, Part II: Numerical Results
(Elsevier, 1993-04-08)
Numerical results for the parametric resonance response of layered anisotropic circular cylindrical shells are presented based on a theoretical development given in part I [1]. The principal regions of parametric resonance ...
