DESIGN AND OPERATION OF A COUNTERFLOW FILL AND NOZZLE TEST CELL: CHALLENGES AND SOLUTIONS

摘要

At the start of the project there were many challenges: define the boundaries of operation of the test cell, achieve uniform L/G, quantify wall water by-pass, pick accurate and redundant instrumentation, establish a "baseline", etc. Research, patience and perseverance are indispensable ingredients to address the challenges one by one. But after several weeks spent debugging and fine-tuning the installation, the baseline tests came out on target. The knowledge acquired from the fill test cell is not enough. The final proof comes from full scale field tests. But this is another story.
