G0801-1-5 Influence of flow on CO_2 hydrate film

Abstract

The objective of the present study is to elucidate the influence of water flow on CO_2 hydrate film thickness. The models are developed based on the heat transfer and the mass transfer to estimate the film thickness. By the heat transfer model, the calculated hydrate film thickness increase as increasing of water flow. On the other hand, by the mass transfer model, the calculated hydrate film thickness decrease as increasing of water flow. These results indicate that the more investigation is needed to elucidate the dominating factor of initial hydrate film thickness changing with flow rate. For this reason we construct the experimental apparatus to be able to generate water flow on the hydrate film to measure the hydrate film thickness experimentally.
