Dry-ice blasting for cleaning: process, optimization and application

Particle laden flow investigations in special purpose dry-ice blasting applications

“…The main findings from these works are compared in Table 1. A significant difference in minimum particle diameter can be seen between Spur et al [4] and the results of Haberland [5] and Redeker et al [6,7]. A difference in velocity ranges can be seen in the outcomes from Spur et al [4] and Haberland [5] compared to Redeker et al [6,7] where the maximum particle velocities encountered are significantly higher.…”

“…The same procedure is used to size the detected particles according eqn (4). It only utilizes the binary matrix I S ** instead of I ** .…”

“…Outcomes from high speed camera (HSC) experiments on conventional convergent-divergent dry-ice blasting nozzles are discussed in Spur et al [4], Haberland [5] and Redeker et al [6,7]. The main findings from these works are compared in Table 1.…”

“…Krieg [8] uses the findings from Spur et al [4] to predict CO 2 particle emerging velocity for basic studies of the cleaning mechanisms, although he states particle diameters and velocities being strongly dependent on system parameters. One significant problem of CO 2 dry-ice blasting is the necessity of utilizing compressed air, which leads to a low energy-efficiency.…”

Influence of geometrical parameters of convergent sleeve on the value of limit stress

“…Both maintaining low temperature and sublimation in standard conditions make the material widely used in the food industry, e.g. in the process of water carbonation, cleaning and disinfecting surfaces or as an input to refrigerated containers [4][5][6][8][9][10][11][12][13][14]. Agglomeration of crystallized carbon dioxide is performed in order to reduce its volume and extend the time of sublimation.…”
