Analysis on Turbulent Debris Flow’s Movement Energy in Circulation Area LIU Li 1, a, WEI Qing Hua2,b 1 College of Applied Science and technology, Chongqing Jiaotong University, Chong Qing, 400074, P.R.China 2 Chongqing Jiao Tong Survey and Design Institute, Chong Qing, 400042, P.R.China allwwqqhh@163.com, bqhwei20005@163.com Key words: turbulent debris flow, circulation area, energy Analysis Abstract: The gully shapes of Debris flow are generally classified into formation area, circulation area and accumulation area, these three sections .
Mudslides forming region are generally located on the upstream watershed for more segments, high mountains around it, a funnel-shaped mountain basin, forming zone often provides initial material sources and part of power for mud-rock flow.
The circulation area is generally located on middle reaches, many canyon terrains, in which the channel is narrow, groove bed is big and loose accumulation material is rich.

Introduction Plastic materials are widely used in our industrial activities nowadays especially in food packaging, biomedical field and in agricultural sectors [1].
Of these materials starch is being the most attractive candidates due to its low cost, ease of availability, renewability [1,3,4,8].

Magnetic fluids unite their fluid characteristic with magnetic property of those strongly magnetizable materials, therefore they offer various opportunities in a wide area of technical applications[3-10].
Adhesiveness drag reduction is a technology which bases on the method of changing physical, chemical and mechanical properties of boundary materials or of inserting gas or liquid nearby the area where is close to the wall of flowing channel with different physical, chemical and mechanical properties from flowing materials.
