The LES and RANS simulations with the Spalart–Allmaras model and SST k-ω model are performed and their performances are validated against the wind tunnel testing. The minimum pressure occurs at an elevation of about 90 degrees, and the maximum pressure occurs at around 20 degrees. The velocity inlet is set up on the left surface of Part A, which represents the cross section of the flow conditioning section. Moreover, the LES is more accurate in predicting the location of boundary layer separation and reproducing the complex flow field behind the dome, and is superior in simulating vortex structures around the dome to further understand the unsteadiness and dynamics in the flow field. The results associated with Case 2-III are further compared to other studies with similar Reynolds numbers using smooth hemispheres in boundary layer flows [ 1, 7].

Both open and suburban terrain configurations are considered for the wind tunnel testing ( Figure 6).

This version of the BBQ Dome is designed to work with the weber GBS grill with the removable middle, it will sit perfectly under this, other style grates may sit a few millimetres lower, this doesn't affect the operation but it may wobble slightly.

In the wind tunnel testing, both open and suburban terrain configurations are considered, and three velocity levels are applied to the dome model.Y. Characteristics of wind pressures on retractable dome roofs and external peak pressure coefficients for cladding design. It’s keeping my misses sane during an extended lockdown period and I’m pretty sure it’s never going to leave her desk. Profiles of TI at different locations (2 m from the inlet, 4 m from the inlet, and the turning table center) are also compared to experimental results in Figure 20b, where stronger fluctuations are encountered than velocity profiles. To reduce measurement uncertainties, the first and last 10 s of each velocity time history are removed, and then the mean wind velocity is determined based on the middle range of the record. Positive pressure occurs on the windward side and negative (suction) pressure occurs at the dome apex and on the leeward side.
