D the strong mass flux, respectively (a) 0.094 m/s and 0 kg/m , (b) 0.094 m/s and 59 kg/m , and (c) 0.53 m/s and 0 as well as the strong mass flux, respectively (a) 0.094 m/s and 0 kg/m2 s, (b) 0.094 m/s and 59 kg/m2 s, and (c) 0.53 m/s and kg/m . 0 kg/m2 s.The coherence evaluation can then be utilised to analyse the temporal pressure signals, for The coherence evaluation can then be applied to analyse the temporal stress signals, a given test, at several heights within the tube. Figure 9 shows 4 spectra calculated at four to get a offered test, at many heights within the tube. Figure 9 shows 4 spectra calculated at distinct heights throughout the identical experiment together with the following manage parameters: 0.8 4 distinctive heights throughout precisely the same experiment with all the following Hesperidin Autophagy control parameters: sm3/h of aeration flow price (i.e., a superficial excess air velocity at the level of the injection of 0.18 m/s), and a particle mass flux of 58 kg/m . The associated heights are identified inside the titles with the subfigures. As Methyl aminolevulinate Purity outlined by the air velocities as well as the evolution with the strong volume fraction with the height, this test should be in the slugging regime. Figure 9a in(a) (b) (c)Figure eight. Three spectra obtained together with the stress signal with numerous experimental configurations of your air veloc ity and the solid mass flux, respectively (a) 0.094 m/s and 0 kg/m , (b) 0.094 m/s and 59 kg/m , and (c) 0.53 m/s and 0 Energies 2021, 14, 7392 13 of 25 kg/m .The coherence evaluation can then be used to analyse the temporal pressure signals, to get a provided test, at a number of heights inside the tube. Figure 9 shows 4 spectra calculated at four 0.eight sm3 /h of aeration flow price (i.e., a superficial excess air velocity at the amount of the different heights through the exact same experiment using the following handle parameters: 0.8 injection of 0.18 m/s), and a particle mass flux of 58 kg/m2 s. The related heights sm3/h of aeration flow rate (i.e., a superficial excess air velocity in the level of the injection are identified within the titles in the sub-figures. In accordance with the air velocities along with the of 0.18 m/s), in addition to a particle mass flux of 58 kg/m . The related heights are identified in evolution with the solid volume fraction with all the height, this test should be inside the slugging the titles on the subfigures. In accordance with the air velocities and the evolution on the strong regime. Figure 9a indicates that the suspension is inside the single bubbling regime just volume fraction with all the height, this test ought to be within the slugging regime. Figure 9a in above the aeration, characterized by numerous distributions of peaks at frequencies greater dicates that the suspension is within the single bubbling regime just above the aeration, char than 1 Hz with compact magnitudes. Along the tube height, the bubbles coalesce to form acterized by a number of distributions of peaks at frequencies larger than 1 Hz with small slugs [16]. At roughly 1 m above the aeration, the frequency distribution is thus shifted to magnitudes. Along the tube height, the bubbles coalesce to type slugs [16]. At roughly 1 reduce values as well as the peaks are much more clearly defined at 0.four.5 Hz and larger magnitudes m above the aeration, the frequency distribution is hence shifted to reduce values and also the (Figure 9b). You will discover still some greater frequencies with low magnitudes, attributed to peaks are far more clearly defined at 0.four.5 Hz and greater magnitudes (Figure 9b). There are actually noise. This spectrum could then be characteristic of wall slugs. Larger within the tube.
