摘要
The main objective of the present work is an investigation of the accuracy and the reliability of numerical predictions of ceiling jets induced by fire plumes, aiming at practical applications to fire-safety planning. Ceiling jet phenomena are studied numerically using the standard k-ɛ model of turbulence. Computed results are compared with basic experimental data. Of particular interest is the dependence of (a) the computational mesh system, (b) the incompressible or compressible flow assumptions, and (c) initial values of k and ɛ at the inflow on the ceiling jet solutions.
