Figure 4
The image contains two sections: a three-dimensional surface plot and a two-dimensional contour plot. The 3 D plot depicts the predicted deposition rate, measured in kilograms per square metre per second, as a function of inlet velocity, measured in metres per second, and the logarithm of temperature, measured in Kelvin. The axes are labelled accordingly, with the Z-axis indicating predicted deposition rate, while the X-axis and Y-axis represent inlet velocity and log Temperature, respectively. The surface uses a gradient across the plotted area. The 2 D plot depicts contour lines representing deposition rates across the same parameters, with specific data points marked using black and red circles. A colour key on the right of the contour plot shows the corresponding deposition rate values linked to the gradient.(a) 3D surface plot and (b) contour plot of the XGBoost predicted deposition rate
