nUMERICAL INVESTIGATION OF LOCAL SCOUR AROUND DIFFERENT SHAPED BRIDGE PIERS AND ITS REDUCTION
nUMERICAL INVESTIGATION OF LOCAL SCOUR AROUND DIFFERENT SHAPED BRIDGE PIERS AND ITS REDUCTION
Developing a numerical model using FLOW-3D software for simulating the scour depth, sediment deposition, fluid dynamics, bed topography of different shaped bridge piers, including cylindrical, square, diamond, hexagonal, airfoil, oblong, and rectangle. Using tapered shape and collar plates to minimize the effect of local scour.
Goal of the project
Investigate the structural pier having the lowest scour depth to prevent the failure of hydraulic structures.
SCOUR DEPTH ANALYSIS
SCOUR DEPTH ANALYSIS
The square pier (blunt edge) has the minimum square depth, and the diamond shape pier (sharp edge) has the deepest scour depth
SCOUR DEPTH ANALYSIS
SCOUR DEPTH ANALYSIS
Its streamlined shape has dramatically affected the airfoil-shaped pier and produced the highest scour depth
EFFECT OF COLLAR PLATES on cylindrical pier
EFFECT OF COLLAR PLATES on cylindrical pier
Multiple collar plates are attached around the cylindrical pier at different positions (Test 1 to Test 10). Test 10 has the lowest scour depth because it has one collar plate below the bed level and one collar plate above the bed level.
COOLING LOAD CALCULATION AND MODIFICATION OF THE SETUP
COOLING LOAD CALCULATION AND MODIFICATION OF THE SETUP
Calculate the cooling load of the refrigeration lab using ASHRAE fundamentals and CLTD ( cooling load temperature difference) method. Installed a central air conditioner.
