Özet

Impinging air jets are widely used in industry for drying, cooling and heating due to high heat and mass transfer coefficients which are developed in the impingement region. High velocity heated air impinging jets have proved to be very effective to enhance evaporative ink drying especially on the rotary presses for the packaging and converting industry. In this paper, to provide data for ink dryer designers, an investigation has been carried out to obtain the heat and mass transfer coefficients which constitute the evaporative drying of thin ink films. Finally, the theoretical results are compared for the constant rate period and falling rate period with some experimental and theoretical results found to be satisfactory particularly for the drying time.
