In the real industrial world, each system experiences various disturbances due to changes in outside weather conditions, flow rates, size errors in equipment manufacturing, as well as uncertainties in interest rates and material properties.
Different variables are examined including the feed water flow rate, the air flow rate, the cooling water flow rate in the dehumidifier and the weather conditions.
Compared with the normal weather, the maximum flow rate decreases15.7%, 19.1%, 32.5% respectively and the free flow speed decreases 4.4%, 7.3%,10.6% respectively because of light rain, moderate rain and heavy rain weather conditions.
The model can predict the water condensation rate as a function of the gas flow rate, ambient weather and the refrigeration system utilized.
The model solves a first order, no-linear differential equation using a 4th order Runge-Kutta numerical method and various input data (weather data, pond characteristics and flow rate data).
In fact, once their own PVWPS model is designed, they can predict its flow rate given the weather forecasts for the following day.
Validation results show that the model satisfactorily predicts the surface temperature and conditions, the degree of snow cover over the heated surface, and outlet fluid temperature given the weather data, inlet fluid temperature, and the fluid mass flow rate.
It slows down the flow rate.
Banana dried at 1 m/s air flow rate was of the best quality in terms of colour, taste and shape when compared to drying at 0.5 and 2 m/s air flow rate while the weather condition and ambient conditions were almost the same for all the cases with negligible difference.
For natural ventilation, strategies limiting the flow rate when outside temperature exceeds internal temperature are found to have no major impact on comfort conditions for the Belgian weather.
