✦ Synopsis

Abstraet--,~ novel heat transfer probe was developed to evaluate heat transfer coefficients between nearfluidized particles and a vibrating heat transfer surface. The periodic motion of the surface caused fluctuations in the instantaneous heat transfer coefficient, h. The parameter affecting the fluctuating amplitude of h was the vibration amplitude of the surface (0.2 and 0.5 ram). The frequency of the applied motion (0, 2, 6 and 10 Hz) affected the frequency of h. At higher frequencies h varied at the applied frequency. However, at the lowest oscillation frequency, 2 Hz, h varied at approximately twice the applied frequency.
