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 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...

Adequate understanding of the combustion and heat transfer characteristics are considered key points for the development of methane engines. In this paper, a methane combustion chamber with 7-elements is simulated under RANS frame with EDC combustion model, and the focus is paid to the influence...
