Test Case Studies
BioMedical Device Design Optimization
Metered dose inhalers (MDIs) are widely used for the treatment of lung diseases, such as asthma. The delivery of the drug to the lung can be as low as 5% of the metered dose. In order to maximize the dose, a patient needs to inhale whilst simultaneously actuating the...
Turbocharger Packaging
Turbocharger suppliers test their devices in idealized conditions i.e. straight inlets with no flow distortions. In reality, the real estate in an engine bay is limited at best which does not afford the luxury of ideal conditions. Subsequently, there is a...
Investigation of cornea graft failure following DMEK surgery
One option for corneal transplants is DMEK (Descemet Membrane Endothelial Keratoplasty). The procedure is outlined here. As described, once the replacement cornea is unrolled and positioned in the anterior chamber of the eye, SF6 or Air is injected below...
Engine Thermal Management
An engine cooling system must work to manage the thermal behaviour of the engine without allowing an individual part to overheat; if one part fails the whole engine will fail. The engine is exposed to both high-cycle fatigue and low-cycle fatigue....
Processing CT and MRI Scans for Simulation
The objective of the study was to demonstrate the process of taking a Medical Scan (either CT or MRI) extracting physical parts of the scan (in this case the carotid arteries) and carry out a simulation with that geometry. ProcessUsing an open source tool...
Friction Stir Welding
Friction welding processes use the heat generated between contacting surfaces that are in relative motion and pressed together to generate hot and clean surfaces to produce a joint. Rotary Friction Welding (RFW) joins two cylindrical cross sections using a...
Focus on Motor Cooling
FTS Engineering Answers is regularly asked to provide insight into the effectiveness of the cooling of electric motors particularly for the overall packaging of the motor within the electric machine, and to optimize the cooling design of electric motors....
