| Abstract: | By studying the shape and geometrical properties of tetrahedral gap in the intermeshing co rotating twin screw, a mathematical model to precisely calculate the volume of tetrahedral gap has been developed in this paper, which was simplified by approximation using a third order spline function, served as a powerful tool for designing and deepening research into twin screw. |
| Keywords: | volume of tetrahedral gap third order spline function cross section curve mathematical model |
