SCALED MODELS IN FIRE RESEARCH

NO FIRE TESTING FACILITY IS LARGE ENOUGH TO COPE WITH THE FULL RANGE OF SIZES OF BUILDING COMPONENTS AND ASSEMBLIES FOUND IN MODERN BUILDINGS. TO EXTEND FIRE TESTING AND FIRE RESEARCH CAPABILITY TO LARGE SCALE CONSTRUCTIONS, AN INVESTIGATION OF THE FEASIBILITY OF REDUCED SCALE MODELS WAS INITIATED. THIS PAPER DISCUSSES SOME OF THE FIRST RESULTS OF THE INVESTIGATION. SIMILITUDE RELATIONSHIPS FOR THERMO- ELASTIC AND THERMO-INELASTIC BEHAVIOR, HEAT TRANSFER, AND MASS TRANSFER ARE DERIVED. THE PHYSICAL RESTRICTIONS IMPOSED BY THE SIMILITUDE RELATIONSHIPS ARE OUTLINED AND DISCUSSED. THE MOST DIFFICULT PHYSICAL RESTRICTION IMPOSED BY THE SIMILITUDE REQUIREMENTS IS THAT OF THERMAL SCALING. THE GENERAL CORRECTNESS OF THE DERIVED SIMILITUDE RELATIONSHIPS FOR HEAT AND MASS TRANSFER EFFECTS WAS CONFIRMED BY TESTS IN WHICH THE MODEL, OF NECESSITY, WAS LARGER THAN THE PROTOTYPE. /PCA/
