Thermal engineering

Goal: The Surgical Company has introduced the Fluido ®. With this medical device, blood and fluids can be heated in a controlled way. It is used in hospitals during operations when patients require a blood transfusion. The Fluido ® can be a life saver when the blood is added at body temperature instead of room temperature, or even lower, especially when the patient requires a large quantity of blood.

Goal: For a high-tech project, a conduction cooling concept based on helium flow is under consideration. The suitability and performance of this method needs to be verified using numerical analysis and experiential verification to qualify the concept. As a rough starting point for the design of the cooling device the in literature found correlation from Norris and Gnielinski have been used. Challenging technical aspect for modeling of this cooling concept are the high mass flow rate through a small channel with large heat fluxes and uncertainty in the wall roughness parameters.
