Noor et al.Problem statement: The variation of the in-cylinder gas flow characteristics for single cylinder port injection hydrogen fueled internal combustion engine was investigated through transient state simulation. Approach: One dimensional gas dynamics was described the flow and heat transfer in the components of the engine model. Special attention is paid to selection and correction of heat transfer correlation which describe of … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 8,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractGermination Ecology of Rhanterium epapposum Oliv.Sameeha Zaman, Shyamala Padmesh, Harby TawfiqProblem statement: Rhanterium epapposum, locally called Arfaj is the national flower of Kuwait. The current situation of Rhanterium epapposum is quite critical in most areas of Kuwait. In fact it has completely disappeared from most parts of the country due to a combination of overgrazing, collecting for firewood and off road driving. Approach: Rhanterium epapposum is an excellent species for … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,618 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplied a Closed-Loop Oscillating Heat-Pipe Heat Exchanger to Increasing Oil Yield in Pyrolysis ProcessN. Panyoyai, T. Wongsiriamnuay, S. SangsrichanProblem statement: A Closed-Loop Oscillating Heat-Pipe (CLOHP) heat exchanger was a heat exchanger with one of the most promising conductivity capacities because of its higher cooling and condensing potential. Therefore, the aims of this study were to design and fabricate a CLOHP to be applied to increasing oil yield in the pyrolysis process. Approach: Two types of oscillating heat-pipe arrangements-parallel … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 7,620 accessesView PDFCite
