For hydrocarbon-fueled turbojet engines with a precooling technology, the precooling technology with a low-temperature endothermic fuel is a great potential way to solve the problem of sharp reduction of the specific impulse caused by the insufficient heat sink of the hydrocarbon fuel. To study...

The insight information of subcooled flow boiling is very important for the development of boiling crisis mechanistic model. In this paper, visual experiment is carried out in a vertical square channel with a heating rod with diameter of 9.5 mm. Based on the near-wall bubble behavior captured by...

R744 is the most competitive, and R744 is the most ideal when flammability and toxicity are strictly limited. There are some problems in the current R744 heating system, for example the pressure at the heat release side is often more than 10.0MPa. High operating pressure brings high cost....

Hydrocarbon-fueled scramjet is one of the most promising air-breathing propulsion systems for hypersonic flight, but the wall thermal protection issue strictly limits its maximum flight Mach number. This study presents a fuel indirect cooling based thermal management system (TMS) scheme, in...

We focus on two particular aspects of model risk: the inability of a chosen model to fit observed market prices at a given point in time (calibration error) and the model risk due to the recalibration of model parameters (in contradiction to the model assumptions). In this context, we use...

In Ivory Coast, mining is one of the major sources of income for local people. Because of mining, jobs have been created thus increasing employment opportunities in rural regions. Moreover, this is a job that does not require a lot of skills, so a lot of people are able to join at the same time...

Using the first-principles calculations based on density functional theory, we investigate the more d-electrons doping effects on the electronic structure and magnetism of the parent inverse Heusler alloy Ti<Subscript>2</Subscript>CoAl by the substitution of Nb and V atoms for Ti(A) and Ti(B) atoms locating at the two...</subscript>

The growth-optimal portfolio optimization strategy pioneered by Kelly is based on constant portfolio rebalancing which makes it sensitive to transaction fees. We examine the effect of fees on an example of a risky asset with a binary return distribution and show that the fees may give rise to an...
