Acid gas removal experiments are carried out in a large bench scale corona radical shower reactor-catalyst hybrid system. A simulated stationary jet engine test cell flue gas is air mixed with NO, SO2 and CH4. NO, NO2 and SO2 concentrations were measured by a Green Line gas analyzer and the trace by-products are determined by Fourier Transform Infra-Red spectroscopy (FTIR). The aerosol particles generated by the acid gases and methane related plasma processes were collected by the electrostatic precipitator operated at !19 kV dc downstream of the reactor. The size of the reactor is (10×30×100 cm) and four pipe with nozzle type radical injectors are placed in series. The corona radical shower electrode used was a 6 mm o.d. tube equipped with 28 hollow electrodes (1.2 mm i.d./1.5 mm o.d.).

A yaw/roll simulation model is developed to assess the dynamic performance of 5, 6, 7, and 8-axle logging truck configurations in this paper. Results predicted by the yaw/roll models for a 5-axle tractor/pole trailer (with outriggers) and a 6-axle tractor/jeep/pole trailer (with outriggers) are compared with those measured in field tests for purposes of model validation. Good agreement between the simulations and measurements has been obtained. Certain performance measures for the tested tractor/pole trailer and tractor/jeep/pole trailer, such as Rearward Amplification Ratio, Load Transfer Ratio, Transient High-speed Offtracking, Understeer Coefficient, Static Rollover Threshold, and Low-speed Friction Demand, are examined by using the yaw/roll models.

A nonlinear yaw-roll model for log hauling trucks is developed in this paper. Several nonlinear effects, such as nonlinear tire cornering forces, nonlinear tire aligning moments, and the coupling between the yaw and roll motions, are considered in this model. Using this model, a computer simulation of the directional and roll responses of a logging truck with tractor and pole-trailer configurations is carried out through various maneuvers. Simulated results for the lateral accelerations are compared with those obtained from field tests. Good agreement has been achieved.

A yaw roll model is proposed for investigating the effect of roll motion and suspension on the lateral dynamic behaviour of various design configurations of log hauling trucks. A detailed kinematic and dynamic analysis of this model for the truck tandem axle pole trailer combinations is carried out, and the corresponding equations of motion are established. The directional response and roll response under step and sinusoidal steer maneuvers are investigated numerically. The results obtained show that the suspension and roll motion have a significant effect on the final steady state motion in the lateral direction.
