A prototype of hydraulic free piston engine has been developed to achieve efficient energy conversion directly from chemical energy of fuel to hydraulic energy. In stable running condition, in order to verify the features of this kind of engine, the piston dynamics, combustion process and...

In this study, a feasibility based inexact fuzzy programming approach (FBIFP) was developed and applied to the planning of a regional electric power generation system (REPGS). As an extension of existing interval linear programming and fuzzy linear programming, FBIFP could tackle uncertainties...

Air preheater is one of key elements in today’s energy-saving technology. Its performance deeply depends on the underlying configuration for heat transfer. In this paper, the pressure drop and heat transfer characteristics of a high-efficiency plate-fin structure used in an air preheater are...
