- W2187436788 abstract "In this PhD thesis, Magnetic Resonance Imaging (MRI) techniques were applied to thermofluid applications. Magnetic Resonance Velocimetry (MRV) was utilized to measure the three-dimensional, three-component mean velocity field in forced convection flows. Flow models were investigated that contain complex internal structures (e.g. compact heat exchangers) that would not be measureable with conventional optical velocity measurement techniques. The effects of the internal structures on the fluid flow were analyzed to understand the flow physics and to introduce further improvements in performance. Modern three-dimensional manufacturing processes, such as direct polyamide laser sintering, were used to manufacture MR compatible flow models of arbitrary complexity. Measuring velocity fields in such flow models highlights the unique features of MRV.Magnetic Resonance Thermometry (MRT), based on the temperature-dependent Proton Resonance Frequency (PRF) shift of the water molecule, is a comparatively novel approach with which the scalar temperature difference field can be measured. Novel experimental setups meeting the requirements given by MRT were developed and applied to MRT and MRV. The chosen flow models were taken from thermofluid sciences and exhibit mixed convection flows, whereby temperature-induced buoyancy forces play an important role. In their velocity and temperature fields three-dimensional structures develop. The three-dimensional temperature and velocity vector fields were measured utilizing optimized adjustments of both techniques. The results show the applicability of MRT and MRV to thermofluid applications and demonstrate these MRI techniques as valuable engineering measurement tools." @default.
