Many researchers have studied the drying process based on mathematical model and simulation in order to predict the temperature and velocity profile of hot air flow in the drying chamber [2-5].
Pimsamarn et al. [3] numerically investigated the distribution of air flow and temperature by using Computational Fluid Dynamics (CFD) of the average exhaust air temperature of 56 °C with air velocity of 1.75 m/s.

In term of fluid flow behaviour, low Re no. calculated from the gained data shows that the entrapped water in the cavity had laminar flow. 0.2Hz 1.0Hz 2.0Hz Fig. 3 Scatterplot of Displacement Fig. 4 Simulation of the oscillating membrane and Input frequency, fin Fig. 5 Fig. 6 Conclusion The Re numbers obtained from the pre-determined input frequency range was between 14 and 35.
Despite obtaining these numbers, the more accurate data of the laminar flow such as the fluid velocity could be anticipated using computational fluid dynamic (CFD) simulation approach.

To estimate the spectrum of possible technological innovations in the existing structure expedient first carry out numerical simulations using fluid dynamics software packages [13-14].
This paper presents the numerical simulation of classical construction of countercurrent cyclone; the results are compared with the calculation for the case of a conical nozzle on the exhaust pipe.

In this paper, the author aims at quantizing the size and shape of courtyard space by advantage of CFD software to seek for internal coordination of climate and space in a rational way.
Analysis of Experimental Simulation Analysis of air speeds at windows and in sports fields.
Therefore, this paper mainly centers on improving ventilation by wind pressure of sports space under hot and humid climate. 2) To get close to actual dimension of the object and for the convenience of simulation, the plan size of basic model a in this paper is set to be 98m*38m, namely, a 44m*38m multi-function Type I sports field plus a 54m*38m multi-function Type II sports field (refer to the Design code for sports building (JGJ 31-2003) in China ).

CFD modeling has emerged as a powerful tool for the prediction of ice shape and for the simulation and optimization of ice protection systems.
The objective of this part is to illustrate that the numerical simulation method presented in this paper can apply to any complex three-dimensional structure.
Applying the numerical simulation technique, ice accretion results are obtained both on NACA0012 and a four-element wing surface.

The shrinkage and collapse of cavity zone and violent changes of the pressure field have been captured during the simulation.
The water exit numerical simulation, by Liu Zhiyong with MAC (Marker And Cell) method and consideration of cavity, indicated the formation of retroreflective water.[9] Quan Xiaobo conducted series of experiment and theory research to investigate the mechanism of cavity collapse.[10] The transient and strong nonlinearity makes the research on cavity flow during water exit very tricky.
To validate the CFD numerical method and computational model, the flow field around the vehicle at three different cavitation numbers has been simulated.
Conclusions The numerical simulation of water exit considering cavity has been conducted.
