Heat Exchangers: Fundamentals and Design Analysis

By Prof. Prasanta Kumar Das, Prof. Indranil Ghosh   |   IIT Kharagpur
Learners enrolled: 1093
Heat exchangers are extensively used in diverse industries covering power generation, refrigeration and air conditioning, cryogenics, oil refineries and chemical processes, automobiles and other transport devices. The performance of a heat exchanger is very important for the conservation of energy, assurance of product quality, process viability and environmental protection. The present course aims at developing a familiarity with various types of heat exchangers, their construction and applications. Conventional methods of heat exchanger analysis; brief design methodology of typical heat exchangers and synthesis of heat exchanger network. It is planned to develop an appreciation and basic expertise in heat exchanger through description, mathematical analysis and numerical examples.



INTENDED AUDIENCE : Mechanical Engineering, Chemical Engineering, Energy Engineering, Cryogenics Engineering, Aerospace Engineering etc.
PREREQUISITES : Thermodynamics, Fluid Mechanics and Heat Transfer (at a very basic level).
INDUSTRY SUPPORT : All the companies generating coal based and nuclear based power (NTPC, different state electricity boards, CPRI,                         
                                            BARC, andNPCL etc.). Companies dealing with the design and fabrication of heat exchangers, auto mobile                                                           industries,  process industries, oil refineries. Companies dealing with waste heat recovery and renewable. Some             specific companies could be      BHEL, ALSTOM, HP, HPCL, IOCL, THERMAX, BPCL, GAIL, Reliance, TATA Chemicals etc.
