Case study-1

• The heat recovery system involves a counter-flow helical heat exchanger.
• Cold water enters the exchanger at a rate of mA kg/s and a temperature of Tc,in oC.
• Engine oil enters the exchanger at a rate of mB kg/s and a temperature of Th,in oC.
• The helical coil has a pitch distance of 100mm.
• The objective is to optimize the rate of heat transfer within the constraints of a 1m length and a fixed outer shell diameter of 250mm.
• Students are required to generate two case studies: a benchmark case and an optimized case.
• The benchmark case corresponds to the boundary conditions provided in the table, based on the last ID of the student P No.
• For the optimized case, students must optimize the design and operation of the heat exchanger while maintaining realistic flow rates.
• The primary constraint is the fixed outer shell diameter of 250mm.
