However, this process becomes slower with the increase of the hole depth.
Hole-textured surfaces with desired hole depth values could be successfully fabricated.
The hole depth is then expected to linearly depend on the etching time.
In addition, the distribution of residual stress varies with various hole depth and work piece thickness is investigated.
It is indicated that the ratio of the hole depth to the hole diameter should be smaller than four.
The hole depth of gas drainage hole is generally no more than 100m, so it can be considered that the aperture is approximately parallel with the opening position.
First, we propose a measurement-based approach that derives a mapping between average albedo of the surface patch containing the hole and the hole depth.
It was found that Cassie state shifting from Wenzel state could be easily achieved with increasing hole depth on TiO2 surface.
By using the measurement system in oblique hole, we can see that with the increase in the hole depth, the measurement results are basically approaching stable value.
Large woody debris (LWD) reduces the flow area, deviate the flow and increases the velocity in correspondence of the bridge pier, therefore increases the maximum scour hole depth and accelerates sediment removal.
To construct ANN models, the maximum charge per delay, distance from blasting face to monitoring point, stemming and hole depth were taken as inputs, whereas peak particle velocity (PPV) was considered as an output parameter.
