Wake development in staggered short cylinder arrays within a channel

  title={Wake development in staggered short cylinder arrays within a channel},
  author={Jason K. Ostanek and Karen A. Thole},
Staggered arrays of short cylinders, known as pin–fins, are commonly used as a heat exchange method in many applications such as cooling electronic equipment and cooling the trailing edge of gas turbine airfoils. This study investigates the near wake flow as it develops through arrays of staggered pin fins. The height-to-diameter ratio was unity while the transverse spacing was kept constant at two cylinder diameters. The streamwise spacing was varied between 3.46 and 1.73 cylinder diameters… CONTINUE READING
