Drill Design

Orthopaedic surgery procedure widely utilizes bone drilling in the work for correcting bone fracture and attaching prosthetics. Clean and accurately positioned holes are desired during bone drilling without damaging the surrounding tissues. However, bone temperature rises during drilling. It is always required to keep the temperature during drilling below 47 °C to avoid thermal osteonecrosis (bone cell death), which might lead to a loose of bone-implant interface. Drill design, drill parameters, and coolant delivery were believed to contribute to heat generation. As complex anisotropic biological tissues, determining the bone temperature during drilling is another issue. Complex mechanical and thermological properties are also other problems to be investigated due to the sensitivity to testing and specimen preparation.

Transfer Flow

The problem of combined free-forced convection and mass transfer flow over a vertical porous flat plate, in presence of heat generation and thermaldiffusion, is studied numerically. The non-linear partial differential equations and their boundary conditions, describing the problem under consideration, are transformed into a system of ordinary differential equations by using usual similarity transformations. This system is solved numerically by applying Nachtsheim-Swigert shooting iteration technique together with Runge-Kutta sixth order integration scheme. The effects of suction parameter, heat generation parameter and Soret number are examined on the flow field of a hydrogen-air mixture as a non-chemical reacting fluid pair. The analysis of the obtained results showed that the flow field is significantly influenced by these parameters.
