Heat transfers through diesel-engine cylinder liners

  • Design


A computer package has been developed, using a finite-element technique, to predict the steady-state rates of heat transfer radially through the cylinder liner, or other axisymmetric components, of a medium-speed diesel engine. Comparisons between experimentally measured and computer predicted results have been made: better corroboration occurs for engine loads above 1034 k N m-2 BMEP. The predictive computer package DIESHT needs only a simple [`]user input' and produces a complete graphical output of generated mesh and computed isotherms. Computational storage requirements are modest so that the program can be used with a CAD system, if required, in order to facilitate an interactive design procedure.
