  33. <meta content="This paper presents flow visualisation experiments
  34. for a novel film-cooling hole, the converging
  35. slot-hole or console for short. Previously published
  36. experimental results have demonstrated that the console
  37. improved both the heat transfer and the aerodynamic
  38. performance of turbine vane and rotor blade cooling
  39. systems. Flow visualisation data for a row of consoles
  40. were compared with that of cylindrical and fan-shaped
  41. holes and a slot at the same inclination angle of 35° to
  42. the surface, on a large-scale, flat-plate model at enginerepresentative
  43. Reynolds numbers in a low speed tunnel
  44. with ambient temperature mainstream flow. In the first
  45. set of experiments, the flow was visualised by using a fine
  46. nylon mesh covered with thermochromic liquid crystals,
  47. allowing the measurement of gas temperature contours
  48. in planes perpendicular to the flow. This data demonstrated
  49. that the console film was similar to a slot film,
  50. and remained thin and attached to the surface for the
  51. coolant-to-mainstream momentum flux ratios of 1.1 to
  52. 40 and for a case with no crossflow (infinite momentum
  53. flux ratio). A second set of flow visualisation experiments
  54. using water/dry-ice fog have confirmed these
  55. results and have shown that the flow through all coolant
  56. geometries is unsteady." name="eprints.abstract" />

  250. for a novel film-cooling hole, the converging&#13;
  251. slot-hole or console for short. Previously published&#13;
  252. experimental results have demonstrated that the console&#13;
  253. improved both the heat transfer and the aerodynamic&#13;
  254. performance of turbine vane and rotor blade cooling&#13;
  255. systems. Flow visualisation data for a row of consoles&#13;
  256. were compared with that of cylindrical and fan-shaped&#13;
  257. holes and a slot at the same inclination angle of 35° to&#13;
  258. the surface, on a large-scale, flat-plate model at enginerepresentative&#13;
  259. Reynolds numbers in a low speed tunnel&#13;
  260. with ambient temperature mainstream flow. In the first&#13;
  261. set of experiments, the flow was visualised by using a fine&#13;
  262. nylon mesh covered with thermochromic liquid crystals,&#13;
  263. allowing the measurement of gas temperature contours&#13;
  264. in planes perpendicular to the flow. This data demonstrated&#13;
  265. that the console film was similar to a slot film,&#13;
  266. and remained thin and attached to the surface for the&#13;
  267. coolant-to-mainstream momentum flux ratios of 1.1 to&#13;
  268. 40 and for a case with no crossflow (infinite momentum&#13;
  269. flux ratio). A second set of flow visualisation experiments&#13;
  270. using water/dry-ice fog have confirmed these&#13;
  271. results and have shown that the flow through all coolant&#13;
  272. geometries is unsteady.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The original publication is available at http://www.springerlink.com/content/100416/</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/290501.html">290000 Engineering and Technology &gt; 290500 Mechanical and Industrial Engineering &gt; 290501 Mechanical Engineering</a><br /><a href="http://eprints.utas.edu.au/view/subjects/290201.html">290000 Engineering and Technology &gt; 290200 Aerospace Engineering &gt; 290201 Aerodynamics</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2259</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Dr Jane Sargison</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">22 Oct 2007 23:22</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=2259;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&amp;eprintid=2259">item control page</a></p>
