Engine power was calculated for each torque output using the equation below.P=τ·2π·N60where: The uncertainties in the measurements taken in the paper are listed below based on the manufacturer's guidelines for the equipment used. These errors have been used in calculating the error in ...
The equation shows the right intuitive behavior for the radiation pressure effect, i.e., no effect for large emissivity when the radiation is saturated, but an effect at low G when r˙c becomes small relative to the radiation term. The kinetic pressure effect arises out of the pressure ...
An integrated numerical model has been developed based on the General Transport Equation Analysis code. The effect of turbulence in the nozzle was considered by the hybrid breakup model in the simulation, and the skeletal mechanism of diesel surrogate fuel and biodiesel surrogate fuel was used to ...
early start of combustion) in a piston engine. The thermal barrier effect induced by the coated piston reduces the adverse effect caused by the high viscosity and density of LPO48. As a result of this, the premixed combustion phase is improved for LPO blends in the coated piston engine. Als...
Biodiesel combustion: Advances in chemical kinetic modeling Burgeoning global demand for energy has increased concerns about the fuel security issues and deleterious environmental impacts that result from the ubiqui... JYW Lai,KC Lin,A Violi - 《Progress in Energy & Combustion Science》 被引量: 149...
The transfer function for the hidden and output layer was Tangent sigmoid. MSE and MRE of the predicted results were 0.002 and 6.8%, respectively. In another study, Lapuerta et al. [89] analyzed the effect of biodiesel on particulate matter emissions. A model was developed to estimate the ...
A robust nonlinear control approach for modern diesel engine operating under low temperature combustion and conventional compressor ignition combustion modes is described. A nonlinear state space model of intake system is established based on the ideal gas equation and the law of mass conversation.The ...
Few months ago I finished a very similar study on a gas turbine fueled with biodiesel, and I had the same doubts !!! So, I can suggest you somethingh. First of all, you have to adopt an unsteady analisys to study a spray phenomena; keep attention about the time step size. As Regard...
Likewise, the regression equation for maximum rate of heat release (MROHR) is given by Eq. (7):(7)MROHR(J/CAD)=30.8+0.138CAD(bTDC)-0.506Ethanol(%)S=1.35111R-sq=97.5% In Eq. (7), the standard deviation of the observed error terms is 1.3511. And, 97.5% R-square indicates that ...
The combustion equation for octane burning with 100.% theoretical air is C8H18+12.5[O2+3.76(N2)]→8(CO2)+9(H2O)+47(N2) Since the products can be considered to be ideal gases, we can useEq. (15.17)and the average specific heat values given inTable 15.5. FromTable 15.1, we find, ...
