Abstract Pneumatic motors have several advantages and many robotics automation applications. The importance of the study is that it a cheap possible way to apply fixed displacement pneumatic with simple directional control valve used. purpose addition any traditional change motor be variable speed torque compared expensive systems such as proportional in industrial also included validated simul...

Cyclic vibratory torque requirement of a Reciprocating Compressor sets in torsional vibrations in compressor motor system. Explanation of development of pulsating currents, due to vibratory motion of motor rotor is given. The pulsating currents are superimposed on steady state currents. Mathematical mod~ls for analysing torsional vibrations of the system and nett motor current due to combinatio...

Prediction of single-sided natural ventilation is difficult due to the bi-directional flow at the opening and the complex flow around buildings. A new empirical model was developed that can predict the mean ventilation rate and fluctuating ventilation rate due to the pulsating flow and eddy penetration of single-sided, wind-driven natural ventilation in buildings. The governing equation is base...

We report that the flow of a liquid on single-walled carbon nanotube bundles induces a voltage in the sample along the direction of the flow. The voltage that was produced fit a logarithmic velocity dependence over nearly six decades of velocity. The magnitude of the voltage depended sensitively on the ionic conductivity and on the polar nature of the liquid. Our measurements suggest that the d...
