Longitudinal vortex generators (LVGs) have the potential to make mini-channel perform thermally better at high heat density and the mentioned fact encourages further investigations. However, innovative shape modifications, parameters and their combinations have not been studied in detail. In the present study, Mini-channels are modified by considering various configurations (co-flow-up, co-flow-down, counter-flow-up, and counter-flow-down) of LVGs. Each channel contains four rows of equally placed LVGs along the side walls. Thermal performance is discussed by analyzing the fluid structure modified due to the induced longitudinal vortices and parameters of LVGS are refined accordingly.

To achieve phase stability, the powders were subjected to heat treatment at 950 °C for four hours. X-ray diffraction (XRD) analysis, combined with Rietveld refinement performed via FullProf, confirmed that the non-doped composition adopts a tetragonal symmetry within the P4mm space group, whereas increasing Mg content promotes the emergence of a hexagonal structure associated with the R-3 space group. For intermediate compositions, a biphasic region is observed, where both tetragonal and hexagonal phases coexist without any detectable secondary structures. Fourier-transform infrared spectroscopy (FTIR) identified distinct vibrational bands in the 450–600 cm⁻¹ range, characteristic of TiO₆ octahedral stretching and bending modes. Scanning electron microscopy (SEM) analysis revealed greater material densification and finer grain size, with the 0.97 Mg sample exhibiting a highly uniform grain distribution and optimal densification. Based on Williamson-Hall analysis, the estimated crystallite sizes fall within 130–154 nm, with an uncertainty margin of approximately 2–5 %.

To show the performance of parameters identification, the PF method is compared with Unscented Kalman Filter method as well. The results show that the particle filtering method effectively identifies the strong nonlinear model with multiple degrees of freedom with partial measurements.
