【 摘 要 】

Nowadays, the exploration of drag reductions by using natural resources has become popular because of its high efficiency in providing positive results and low cost comparing with other proposed technologies. This paper focuses on applying the chitosans, the polypeptide in aquatic live and the chitin, in a flowing liquid to improve the systems in plummeting drag reductions. As natural fluid resource, water is used as the reference flowing fluids for drag reduction with fixed volume. By employing different types of acid with various proportionate volumes of chitosan, it demonstrates positive results of decreasing drag. In addition, when the concentrations of the additive solutions are increased, the drag reduction process appears more effected. Finally, the most incredible results are convinced to be obtained in forms of 80.842% drag reductions from the chitosan solutions prepared with hydrochloride acids.
