Effect of mist/steam uniformity on heat transfer characteristics in unconfined jet impingement

“…Figure 2a shows the local Nu number along the heated wall for computational and experimental results [5,26,27]. A circular free jet shape is modeled at z/D = 6 and Re = 23,000, the inlet flow is considered as a fully developed flow at the heated wall, and the thermal flow was fixed at Q = 7.54 kW•m -2 .…”

“…A remarkable number of researchers have investigated the jet impingement features in confined conditions [2][3][4][5][6][7][8][9][10]. Previous research has highlighted attempts to increase the heat transfer of confined synthetic air jets using ducting plates with the distance from the jet exit assisting to draw cold air in with the jet flow [11].…”

A lattice QCD perspective on weak decays of b and c quarks Snowmass 2022 White Paper

“…In addition, the use of QCD factorization to describe nonleptonic decays is under scrutiny due to observed large discrepancies with experimental results. Summaries and further details can be found, for example, in [1][2][3] and in recent reviews of lattice calculations [4][5][6][7]. Currently no single quantity is considered significant and trustworthy enough to claim a smoking gun signal for new physics.…”
