This course aims to provide the necessary knowledge that will enable students to analyze and design the most popular heat exchangers under conditions of single‐phase and multi‐phase heat transfer. Thus, the fundamentals of gas/liquid multiphase flow, film condensation and pool and flow boiing are also
covered.

Preliminary thermal design of heat exchangers. Fouling and scaling problems. Basic exchanger types. Design of double‐pipe exchangers. Construction details, TEMA classification and design of shell‐and‐tube exchangers. Design of compact heat exchangers, tube‐and‐fin, plate‐and‐fin and plate‐and‐frame. Two phase pressure drop and heat transfer computations. Physics of condensation and design of condensers. Nucleate and film boiling. Critical heat flux in pool and flow boiling. Design of evaporators and reboilers. Steam and energy economy. Fire‐tube and water‐tube boilers. Construction details, operational characteristics and energy calculations of boilers. Water‐steam and fuel‐exhaust circuits. Design considerations for the combustion/radiation chamber
