![]() ![]() Both types of simulation reproduce the unsteady flow physics, and much information can be extracted from the results when investigating frequency content, the location of unsteadiness, and its amplitude. Time-accurate Reynolds-averaged Navier–Stokes and delayed detached–eddy simulations are then performed on the adapted grid. Based on exploratory simulations using a baseline grid, the region relevant to the phenomenon is identified and mesh adaptation is applied to significantly refine the grid locally. Results indicate the presence of shock-wave oscillations inducing unsteady loads that can cause serious damage to the aircraft. The Mach number is close to cruise conditions, whereas the high angle of attack causes strong separation on the suction side of the wing. #IGAD paper presents a numerical study of the transonic flow over a half wing–body configuration representative of a large civil aircraft. Good news coming in as #Ugandan Jacob Kiplimo won the men's race at the #NYC Half Marathon with 1:01:31, beating his compatriot Joshua Cheptegei. At the 15K checkpoint, they were a few seconds clear of Kenya’s Edward Cheserek, and the previously tight-knight top 20 had spread out considerably. It was over the next 5K that Kiplimo, Cheptegei and Morocco’s Zouhair Talbi went to work, slowly pulling away from the rest of the field. The chase group featured Kiplimo, Cheptegei, Linkletter and 15 other men, all of whom were within two seconds of each other.īy 10K, Thompson’s lead had almost disappeared, and he only had a two-second gap over the chase pack (which still consisted of 16 runners). started off hot, running 15 minutes flat over the first 5K and opening up a 14-second gap over Kiplimo and the rest of the field. Unlike the women’s race, in which Obiri and Teferi took control right away, it took a while for the men to sort out who would take the top few spots. Kiplimo finished well off his half-marathon world record of 57:31 on Sunday, but he still laid down a dominant performance. ![]() Wodak was just behind Huddle in eighth place, posting a final time of 1:12:33. Teferi finished in second in 1:07:51, and Norway’s Karoline Bjerkeli Grøvdal crossed the line in third, well back of the top two in 1:09:53.Īmericans Des Linden and Huddle also notched top-10 results, finishing fifth and seventh. She crossed the line in 1:07:21, taking the win and beating Teferi’s course record by 14 seconds. Obiri’s lead only continued to grow over the next 6K, and by the end of the race, there was a 34-second gap between her and Teferi. United airline NYC half marathon winners of the half marathon Helen Obiri 01:07:21 Jacob Kiplimo 01:01:31. By 15K, however, Obiri had moved seven seconds ahead of Teferi. They covered the first 5K in 15:50 (at which point they were already 20 seconds ahead of the next-closest runners) and passed through 10K at around 31:30. They opened up a sizeable lead early, and proceeded to run almost side by side for more than half the race. Right from the start of the race, it was clear that either Obiri or Teferi would take home the win in New York. Obiri owns the fifth-fastest half-marathon result in history, with a PB of 1:04:22, and she showed the rest of the women’s field why she’s one of the all-time greats on Sunday. She came back this year looking to defend her title and potentially lower the record even more, but Obiri refused to let that happen. In 2022, Teferi broke American Molly Huddle‘s course record from 2016 with a winning time of 1:07:35. □□’s Amedework Walelegn was a comfortable winner of the Seoul International Marathon in a 2️⃣:0️⃣5️⃣:2️⃣7️⃣ PB □įor the second straight year, the NYC Half saw the women’s course record fall. Two-time world 5000m champion and world cross-country champion produced dominant performances at the United Airlines NYC Half on Sunday Canadians Natasha Wodakand Rory Linkletter also raced, finishing as eighth female and 15th male. Kiplimo used a quick closing 5K to pull away from compatriot Joshua Cheptegei and post a final time of 1:01:31. Obiri took the win in 1:07:21, breaking the course record set in 2022 by Ethiopian Senbere Teferi, who finished second on Sunday. Olympic medallists Hellen Obiri of Kenya and Jacob Kiplimo of Uganda won the United Airlines NYC Half on Sunday, both crossing the finish line with comfortable margins of victory.
