TRANSIENT FLOW THROUGH DOORWAYS PRODUCED BY TEMPERATURE DIFFERENCES.

Author(s) : LANE-SERFF G. F.

Summary

NOTES HOW AIR FLOW THROUGH DOORS CAN ACCOUNT FOR A SIGNIFICANT PART OF TOTAL HEAT LOSSES IN HOUSING. DERIVES EXPERIMENTAL DATA FROM LABORATORY EXPERIMENTS USING SALT AND FRESH WATER TO MODEL THE BUOYANCY DIFFERENCES BETWEEN THE COLD AND WARM AIR FOR 1) AN OPEN DOOR AT THE END OF A PASSAGE AND 2) AIR EXCHANGE IN A LARGE WAREHOUSE. REVIEWS THEORETICAL AND EXPERIMENTAL RESULTS FROM GRAVITY CURRENT AND LOCK-EXCHANGE FLOWS IN THE LABORATORY AND USES THE RESULTS TO SHOW THAT SIMPLE MODELS PROVIDE BOTH PHYSICAL INSIGHT AND ACCURATE ESTIMATES TO THE AIR FLOWS AND ASSOCIATED HEAT LOSSES AND/OR GAINS THROUGH OPEN DOORS.
