These measures significantly reduce the resistance and laminar flow zone in the shell side. The gas pipe connection orientation on the shell side can be freely selected.
这些措施显著降低了壳程阻力和滞流区，壳程的气体接管方位可任意选定。

For the three-zone model, a set of coupled correlations has been derived to describe the effect of pressure and temperature on the laminar burning velocity and the laminar flame thickness.
