EFFECTS OF VOLUME FRACTION OF NANOPARTICLE IN LAMINAR FLOW OF WATER ALUMINUM OXIDE IN HORIZONTAL CHANNEL

摘要: NOWADAYS, AN IMPORTANT PROBLEM IN DESIGN OF HEAT EXCHANGER IS ENHANCEMENT OF HEAT TRANSFER WITH REDUCING THE SIZE OF HEAT EXCHANGER. COMMON FLUID, SUCH AS WATER OR OIL HAS LOW CONDUCTIVITY. ONE OF THE NEW METHOD FOR MODIFYING THE PHYSICAL PROPERTY IS ADDING TINY METAL AND NONMETAL PARTICLE TO BASE FLUID, THUS, THE NEW NANO-FLUID HAS THE HIGHER CONDUCTIVITY RATHER THAN BASE FLUID. LAMINAR TWO PHASE FLOW OF WATER-ALUMINUM OXIDE IN RECTANGULAR THREE DIMENSIONAL CHANNEL WITH CONSTANT HEAT FLUX IS NUMERICALLY STUDIED. IN THIS DISCUSSION, ALL PROPERTY WITHOUT DENSITY, AS ESTIMATED WITH BOSINESQUE APPROACH, ARE CONSTANT. THUS, THE BUOYANT FORCE IN CHANNEL AFFECTS THE FLOW OF NANO FLUID. AT THIS RESEARCH, WE DISCUSS THE EFFECTS OF CHANGE OF VOLUME FRACTION ON THERMAL AND HYDRODYNAMIC DIMENSIONAL PARAMETER, AND ANALYZE RESULTS.
