An Update of Non-iterative Solutions for Surface Fluxes Under Unstable Conditions
نویسندگان
چکیده
A new non-iterative approach has been developed to calculate surface fluxes. The range −5 ≤ RiB < 0, 10 ≤ z/z0 ≤ 105 and −0.5 ≤ ln(z0/z0h) ≤ 30 is divided into eight regions, and in each of the regions, multiple linear regression is performed to obtain non-iterative solutions for surface fluxes. As compared to the other two most recent noniterative schemes, we show that the suggested scheme has the smallest bias. The maximum relative errors of turbulent transfer coefficients for momentum (CM) and sensible heat (CH), as compared to those obtained from the classic iterative method, are always smaller than 2 % from our new non-iterative scheme.

An improved non-iterative surface layer flux scheme for atmospheric stable stratification conditions
Parameterization of turbulent fluxes under stably stratified conditions has always been a challenge. Current surface fluxes calculation schemes either need iterations or suffer low accuracy. In this paper, a non-iterative scheme is proposed to approach the classic iterative computation results using multiple regressions. It can be applied to the full range of roughness status 10≤ z/z0 ≤ 105 and...

In this article, we investigate sufficient conditions for existence of maximal and minimal solutions to a coupled system of highly nonlinear differential equations of fractional order with mixed type boundary conditions. To achieve this goal, we apply monotone iterative technique together with the method of upper and lower solutions. Also an error estimation is given to check the accuracy of th...

In this paper, nonlinear dynamic behaviour of the carbon nanotube conveying fluid in slip boundary conditions is studied using the variation iteration method. The developed solutions are used to investigate the effects of various parameters on the nonlinear vibration of the nanotube. The results indicate that an increase in the slip parameter leads to a decrease in the frequency of vibration an...
