Wind affects adversely the cooling tower thermal performance. A field investigation was carried out to study the thermal performance of Heller cooling towers under wind conditions, involving measurement of wind velocity and its direction around the cooling tower, and obtaining water flow rates and temperatures at the cooling tower inlet and outlet. Results show that air suction at the tower top...

In this paper we consider the Optimized Airspace Sectorization Problem (ASP) with constraints in which a given airspace is to be partitioned into a number of sectors. The objective of ASP is to minimize the coordination workload between adjacent sectors. We proposed a constraint programming approach to optimize the sectorization that shall satisfy all specific constraints e.g. the controllers’ ...
