However, when the objective is to predict 3-s (three seconds) peak loads, large models can be tested in a flow that has reduced high-frequency turbulence. While mean loads are not significantly affected by the model size, peak loads are sensitive to both the geometric scale and the spectral content of the test flow. The current paper systematically investigates the sensitivity of wind loads to testing ground-mounted solar panels, both experimentally (in a BLWT) and numerically (by computational fluid dynamics (CFD)), at different geometric scales. Such protocol should account for different time and geometric scales to design appropriate wind tunnel experiments that can allow accurate assessment of wind loads on the solar panels. To alleviate these problems, development of a standardized testing protocol is very important. Second, the test model may be placed in the lower portion of the boundary-layer that is not a true representative of a real world scenario, due to high uncertainty in wind velocity. DIN 1055-6:2005-03 ppei complementary reference surface loads during discharge ppe. First, the resolution of pressure data on such small models becomes low. DIN 1055-6:2005-03 phco asymptomatic horizontal load at a great depth. This includes the whole structure or parts of the structure or elements attached to the structure, e. However, producing aerodynamic models of the solar panels at such scales makes the modules too small, resulting in at least two technical problems. 1.1 Scope (1) EN gives guidance on the determination of natural wind actions for the structural design of building and civil engineering works for each of the loaded areas under consideration. Most boundary-layer wind tunnels (BLWTs) were built for testing models of large civil engineering structures that have geometric scales ranging from 1:500 to 1:100.
