Though implicit schemes are unconditionally stable as compared to explicit time integration method, the reduction in the cell size as a result of the grid refinement to capture the flow physics imposes severe numerical limitation on the allowable global timestep, which can be represented as the maximum allowable CFL number.
Pitch-up movement Pitch-down movement Fig. 3 Adapted grid and Mach number variation in the domain Comparison of the variation in lift and moment coefficients during pitching motion as shown in Fig. 4 show a good agreement with the experimental data.
The numerical accuracy of the current scheme is demonstrated by comparison with the available experimental data and with the solutions using a pre-existing Mid-point scheme.

First, it has nearly 8192 Bytes Flash Read Only Memory (Rom) and it can be updated by the application program, which resolve the difficulty of storing data.
In the typical microchip, it must store the data to the external memory parts, which increase Printed Circuit Board (PCB).

It has been proved that, with every reduction in mass of 100 kg, the consumption of fuel will be decreased by approximately 0.41/100km [1], and the CO2 emissions will be reduced by 8~11g/km [2].
Therefore, as many as possible aluminum extruded profiles are utilized in original CAD data, as Fig.2 shows.
The CAD data of aluminum CCB is imported to Hypermesh, a professional CAE pre and post processing software, to established finite element model.

Data collection.
With calculation based on product production mass per unit (kg), data collection list of various thermal insulation materials determined in the research is detailed in Table 1.
Through the investigation in typical enterprises in China, we obtain the raw material per unit product consumed, energy consumption and transportation data involved in the production phase of three categories of thermal insulation materials.
The polyphenyl board and polyurethane rigid foam board may be neglected in data collection in view that very little additives such as dispersion agent, initiating agent and flame retardant is applied in production.
The upstream process data involved in the research is from the international and domestic public database [8-10], see Table 2.

Furthermore, the experimental data available are limited.
The value of the calculated molecular descriptor and the experimental debromination data in this study are listed in Table 3.
b Part of the experimental data in the table were collected from the references [7,13,14] and calculated by Zhuang et al. [14].
One principal component (PC1) was extracted from the original data accounting for 86.156% of the total variance using the PCA-MLR approach.
There are some deviations between the prediction results and the experimental data.

Methodology
2.1 Validation of Numerical Model
The numerical model is validated using experimental data from Plew's [17] laboratory studies.
The mean velocity u/Uo velocities within the canopy region and free region (as shown in Fig. 1) were validated by comparing computational and experimental data.
In the vegetation-covered portions of the FVIs patches, experimental and numerical data demonstrate that the mean flow velocities are drastically lowered.
The outcomes demonstrate that the computational data and experimental data exhibit strong agreement, demonstrating the viability of the current numerical model.
Conversely, discrepancies in experimental data may also occur due to unavoidable human measurement errors during the experiment.

As a cost and weight reduction tool, SPF
also offers detail part and fastener reductions through the consolidation of separate stiffeners and
multiple compound contour shaped detail parts into a single monolithic design.
The machine features a digital control system and automated data calculation for roughness parameters.
The data above is from FSW welds made at a constant feed rate of 1.27 mm/s, while varying the rotational velocity of the spindle RPM.
The data in a) is taken from the advancing side, b) is taken from the center and c) is taken from the retreating side of the weld.
The data points are linked with the dashed line that approximates their behaviour and from this it can be seen that PHR = 45 is the point in which a P/W ratio equal to 1.0 is observed.
