Generalization of the Split Flow Heat Exchanger Geometry for Enhanced Heat Transfer

By: K.P. Singh and Michael Holtz Published: AIChe Symposium Series Year: 1979 Abstract: Governing equations for heat transfer in a split flow heal exchanger with four tube passes are derviecl. Using lheso equations, curves for…

Analysis of Temperature Induced Stresses in the Body Bolts of Single Pass Heat Exchangers

By: K.P. Singh, Maurice Holtz Published: ASME Winter Annual Meeting Year: 1979 Abstract: In-plane thermal expansion of mating flange elements of heat exchangers can in-duce severe bending stresses in the body bolts. A design-oriented solution…

Heat Transfer Characteristics of a Generalized Divided Flow Heat Exchanger

By K. P. Singh Abstract: The concept of a "Divided-flow" heat exchanger is generalized by locating the shell inlet (or outlet) nozzle off-center such that the two shell sub-streams are unequal and traverse unequal flow paths.…

Tube stresses due to in-plane thermal expansion of tubesheets in closely spaced double tubesheets

By: Alan I. Soler Published: International Journal of Pressure Vessels and Piping Year: 1978 Abstract: An approximate analysis of thermal stresses developed in heat exchanger tubing between closely spaced double tubesheets is presented. Tube loading…

Analysis of Vertically mounted Through-Tube Heat Exchangers

By: K.P. Singh Published: Journal of Engineering for Power Year: 1978 Abstract: A computer-oriented method for axisymmetric stress analysis of integral tubesheet exchangers is developed. The tubesheet is modeled as a composite plate consisting of…

Analysis of Closely Spaced Double Tubesheets Under Mechanical and Thermal Loadings

By: A.I. Soler Published: American Society of Mechanical Engineers Year: 1978 Abstract: The field equations governing structural behavior of double tubesheet configurations are formulated using beam-column and plate theory including shear deformation. The resulting system…
