Experimental analysis of the wake of a horizontal-axis wind-turbine model (2014, unknown): “[12,14,15] and [23].”
Lagrangian and Eulerian pressure field evaluation of rod-airfoil flow from time-resolved tomographic PIV (2011, methodology): “Furthermore, the question of whether the pressure gradient should be estimated from either an Eulerian (Baur and Kongeter 1999) or a Lagrangian approach (Liu and Katz 2006) has not been fully answered and experimentally verified.”
Tomographic PIV: principles and practice (2012, methodology): “The governing equation is based on the determination of the material derivative of the velocity (Liu and Katz 2006), which can be measured in three dimensions by tomographic PIV both in the case of thin and thick illumination volume.”
Multi-frame pyramid correlation for time-resolved PIV (2012, background): “…Wieneke LaVision GmbH, Anna-Vandenhoeck-Ring 19, 37081 Göttingen, Germany to evaluate the Lagrangian acceleration of fluid particles and in turn integrate the spatial field of the pressure gradient (Liu and Katz 2006; Haigermoser 2009; Charonko et al. 2010; Violato et al. 2010).”
PIV uncertainty quantification by image matching (2013, background): “In 3D data from incompressible flows, the fluctuating velocity divergence (Liu and Katz 2006, Scarano and Poelma 2009) indicates the error level of the velocity and its derivatives.”
Assessment of pressure field calculations from particle image velocimetry measurements (2010, methodology): “Based on the experience of Liu and Katz and testing during this study, it was noted that ten iterations were sufficient to converge most fields below a residual of 10−2 (calculated from the L2 norm of the pointby-point pressure difference divided by the L2 norm of the previous pressure field).”
PIV-based pressure measurement (2013, methodology): “In a series of studies Liu and Katz (2006, 2007, 2008) have reported extensively on the investigation of cavitation in a cavity flow by means of a dual-PIV system, consisting of 2 lasers and 2 cameras, with each system separated by orthogonal polarization.”
