Development of coated, annular fins for adsorption chillers

The specific cooling power (SCP) of adsorption chillers could be increased by employing zeolite coated, extended heat transfer surfaces in the generator. An experiment featured 50 annular aluminium fins, 76 mm diameter, each coated with 2 g of zeolite CBV901, and pressed onto a 10 mm bore aluminium tube. A large (4 kg), structurally stiff and easily fabricated casing enclosed the finned tube…

An experimental investigation of the performance and gaseous exhaust emission…

Experimental tests have been carried out to evaluate the performance and gaseous emission characteristics of a diesel engine when fuelled with vegetable oil and its blends of 25%, 50%, and 75% of vegetable oil with ordinary diesel fuel separately. Tests on ordinary diesel fuel have also been carried out for comparison purposes. A series of tests are conducted and repeated six times for each …

A new diesel oxygenate additive and its effects on engine combustion and emis…

2-methoxyethyl acetate (MEA) can be used to decrease exhaust smoke as a new oxygenated additive of diesel. Several fuel blends which containing 10%, 15% and 20% MEA were prepared. The effects of MEA on engine’s power, fuel economy, emissions and combustion characteristics were studied on a single cylinder DI diesel engine. Under the same speed and load conditions, the maximum cylinder pres…

A two region simulation model of vertical U tube ground heat exchanger and i…

Heat transfer around vertical ground heat exchanger (GHE) is a common problem for the design and simulation of ground coupled heat pump (GCHP). In this paper, an updated two-region vertical U-tube GHE analytical model, which is fit for system dynamic simulation of GCHP, is proposed and developed. It divides the heat transfer region of GHE into two parts at the boundary of borehole wall, and …

Diesel emission improvements by the use of oxygenated DME/diesel blend fuels

A kind of oxygenate fuel, DME, has been proposed and tested for use with diesel fuel as a means of reducing exhaust emissions. The addition of DME to diesel fuel results in the decrease of the lower calorific value, aromatics fraction and kinematic viscosity of blend fuels. Simultaneously, cetane number, C/H ratio and oxygen content of the blends are enhanced, which has some favorable effect…
