The distribution of wall pressures in yawed flow through an array of cylindrical tubes inclined at different angles between 30° and 90° was experimentally studied using air at atmospheric pressure for 2290 ≤ Re ≤ 6100. The experiments show that the pressure coefficient is strongly influenced by the inclination angle, and only marginally affected by the flow rate within the tested range. The pressure behavior at the gap was calculated by assuming curved streamlines and inviscid flow, showing good agreement with measurements performed at the rod wall in the gap position.

In recent years, the food industry has evolved dramatically showing Argentina's real capacity for food production. A survey on supply chain management was developed and data were collected from both suppliers and buyers at three levels of the supply chain. Statistical significance in difference of means for both groups is analyzed and drivers and trends emerging from those samples are shown.
