The method to improve the heat sink utilization of fuel is the primary issue for thermal management of advanced aeroengines. In order to study the methods to control the fuel heat sink utilization, a one dimensional model of flow and heat transfer process in a single cooling channel of...

Thermal management of fuel is very important for the cooling system of an advanced engine. In order to study the 3-D phenomena of fuel flow with cracking reaction in the cooling channels and their effect on the utilization of fuel heat sink, numerical models of cracking fuel flow in an...

In order to evaluate the performance of a new power generation system in which the generator is driven by the fuel vapor turbine, the pyrolysis characteristics and the compositions of pyrolyzed fuel mixture are experimentally studied. An algorithm is developed for the calculation of isentropic...

Advanced aeroengine with endothermic hydrocarbon fuel cooling works as chemical recuperative cycle. In order to study the thermal management of fuel in view of chemical recuperation, models of flowing cracked hydrocarbon fuel inside engine cooling channels are developed and validated. Based on...

In this paper, we discussed the feasibility of early recognition of highly cited papers with citation prediction tools. Because there are some noises in papers’ citation behaviors, the soft fuzzy rough set (SFRS), which is well robust to noises, is introduced in constructing the case-based...

In this paper, we investigated the influences of the age of papers on the preferential attachment on the basis of three actual citation networks. We found that the time dependence of the attachment rate Π(k,t) follows a uniform exponentially decreasing function, T(t)∼exp(−λt), in different...

In this paper, we investigated the preferential attachment mechanism (PAM) by considering the dynamic property in papers’ in-degree k for three citation networks. We found that the past citations obtained in different years will have different influences on papers’ attachment rate Π(k,t)....

The aim of this work is to provide an upper estimate of the theoretical maximum specific thrust of the hydrocarbon fueled scramjet. An idealized thermodynamic cycle analysis is carried out to evaluate the performance of scramjet engines at different flight conditions, inlet pressure ratio and...

The mean work required to drive a bistable system from one equilibrium state to another is calculated by using a Langevin simulation combined with Monte Carlo sampling. The resulting work depends not only on the proposal form but also on the temperature, because the particle subjected to thermal...
