Abstract
The thesis deals with the investigation of the flow behaviour of collagen material. Literature search focused on collagen material description, the flow behaviour of collagen, experimental techniques to obtain information about flow behaviour of collagen material and theoretical approaches to explain and describe of the flow of material similar to collagen. From the literature search, the best device for measurement collagen material in the form of dough is slit rheometer. There are lack information about rheology of collagen material. Pure viscous power-law model or Herschel-Bulkley model are used for the flow description of collagen material. The experiment results from literature were used for the rheology of collagen investigation. Measurements were performed on slit rheometer with three different capillaries. Slits have a rectangular shape with constant width and various thickness of 2, 4 and 8 mm. This thesis uses regression analysis done on the slit rheometer with different heights. The power-law model and Herschel-Bulkley model are applied after regression analysis. Data is obtained from 5 different pressure transducers and evaluated in my own script in MATLAB. The exit pressure relation for slit rheometer is also covered in this work.
