How to handle 2 MW of power in a matchbox-sized target
Radioisotopes are widely used for medical diagnostics and treatment such as cancer care. In particular, the Mo-99/Tc-99m system is the…
EFI OptiGrip – thermal simulations to avoid overheating
With so-called keyhole surgery, thin tubes enter the body via small incisions. Grippers on the tip of these tubes manipulate…
Stabilizing Cooling Flow – prevent cavitation with Inserts
Goal: A liquid cooling system is often used when a high heat load is present on a key component of a system, for a long period. To prevent damage due to the heat, the coolant must continuously...
Custom silencer for flywheel module
Problem: HITEC Power Protection is a world-leading supplier of dynamics (kinetic energy) based UPS (uninterruptible power supply) systems. These UPS systems are supplied into a variety of markets such as datacenters, finance and semicon.
Key components in the system are a flywheel...
Fluido – Design of a heater for blood and fluid using CFD simulation
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.
Qualification of helium flow cooling concept
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.
Design and performance validation of a high performance heating system
Goal: A high performance heating system is required for a proof of principle experiment. This to experimentally simulate the heating effects of a high intensity electron beam exposing a target.
The heating system has to depose 26kW on a metal workpiece...
