Validation of CFD Modeling and Simulation of a Simplified Automotive Model
In the early design phase of automotive sector, the flow field around the vehicle is important in decision making on design changes. It would consume a lot of money and time for multiple prototypes development if adopt traditional testing method which is wind tunnel test. Thus, numerical method such as Computational Fluid Dynamics (CFD) simulation plays an important role here. It is very often ...
متن کاملa Simplified Model of Distributed Parameter Systems
A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...
متن کاملA New Approach in Developing Optimal Defrost/Demist Performance in a Passenger Car (TECHNICAL NOTE)
The objective of this paper is to optimize defrost/demist performance in a vehicle. However, to initiate the problem, it is necessary to have a thorough understanding of flow behavior within the compartment. So a full-scale model of passenger compartment has been modeled and the air stream from very near to the windshield up to back of the compartment has been analyzed applying computational fl...
متن کاملAdaptive Simplified Model Predictive Control with Tuning Considerations
Model predictive controller is widely used in industrial plants. Uncertainty is one of the critical issues in real systems. In this paper, the direct adaptive Simplified Model Predictive Control (SMPC) is proposed for unknown or time varying plants with uncertainties. By estimating the plant step response in each sample, the controller is designed and the controller coefficients are directly ca...
متن کاملA Simplified Model
A simple set of equations for bubbly flow through a vertical tube is rigorously derived by means of a scale analysis from the realistic equations posed by Pauchon. It is shown that under steady flow conditions the void fraction will relax from its value at the inlet towards an asymptotic value within only a short distance of the inlet. The relationship between the inlet void fraction and the im...
