Design of a natural dry cooling tower has been accomplished in two sections: the design of heat exchangers and the numerical solution of flow through the tower. Heat exchanger (Heller type) has been simulated thermodynamically and then coupled with a computer program, which calculated the turbulent natural convection flow through the tower. The computer program developed for this purpose can be...

The Cooling Tower Energy & Operating Cost Analysis Software is an in-house program developed by Tower Tech and is used to design and evaluate the performance and life-cycle costs associated with a cooling tower. This version can be used to estimate the cost to purchase and operate a Tower Tech cooling tower and a competitor’s tower. A number of assumptions about the details of the competitor’s ...

in a steam power plant, the temperature of the cooling water leaving the condenser for recyclingshould decrease. this is achieved in a cooling tower. the heller cooling tower does not require waterfor operation, thus, it is a suitable system for use in thermal power plants throughout iran. wind is anenvironmental factor that unfavorably affects the performance of a cooling tower. previous studi...

This paper presents an electromagnetic transient analysis of lightning-initiated overvoltage stresses the step-up transformers installed inside a nacelle onshore, multi-megawatt, new-generation wind turbines. The increase in turbine (WT) nominal power output, necessitated introducing transformer into nacelle. A is subjected to completely different from those present if it were at base WT tower....

At present, the calculation method of ice load on surface navigation ships has been very mature, but submarine is few. The reasonable evaluation become an urgent problem to be solved. In this paper, mechanical characteristics surfacing ice-breaking process are systematically analyzed. Based theory plate and shell, theoretical models resistance command tower hull established, respectively, obtai...

We present a new explicit tower of function fields (Fn)n≥0 over the finite field with ` = q3 elements, where the limit of the ratios (number of rational places of Fn)/(genus of Fn) is bigger or equal to 2(q2 − 1)/(q + 2). This tower contains as a subtower the tower which was introduced by Bezerra– Garcia–Stichtenoth (see [3]), and in the particular case q = 2 it coincides with the tower of van ...

Abstract With the upsurge of digital twin power grid, it is very necessary to carry out a three-dimensional model and simulation analysis grid system. Insulators are one important components in system, appropriate simplification great significance. In this paper, finite element software used calculate model, influence length conductor, tower, yoke plate, grading ring, arrangement insulators on ...

This article is the second in a two-paper series presenting results from wind tunnel and computational fluid dynamics (CFD) simulations of flow and dispersion in an idealized model urban neighborhood. Pollutant dispersion results are presented and discussed for a model neighborhood that was characterized by regular city blocks of three-story row houses with a single 12-story tower located at th...
