In this paper, performance evaluation of wet cooling tower is done. To achieve this aim, first, thermal behavior of counter-flow wet cooling tower is studied through a simulation model. The influence of the environmental conditions on the thermal efficiency of the cooling tower is investigated. The cooling tower performance is simulated in terms of varying air and water temperatures, and of the...

Throughout the years, the importance of the maintenance management system and their functions has grown rapidly. Cooling towers are used in many process applications in the various industries. Reliability of these towers is crucial. In many cases, redundant towers are installed to ensure a process will not have to be stopped due to a cooling tower failure. The most prevalent cause of cooling to...

We consider the problem of classifying the orbits within a tower of fibrations with P-fibers that generalize the Monster Tower due to Montgomery and Zhitomirskii. The action on the tower is given by prolongations of diffeomorphism germs of 3-space. As a corollary we give the first steps towards the problem of classifying Goursat 2-flags of small length. In short, we classify the orbits within t...

A tower is a sequence of simplicial complexes connected by simplicial maps. We show how to compute a filtration, a sequence of nested simplicial complexes, with the same persistent barcode as the tower. Our approach is based on the coning strategy by Dey et al. (SoCG 2014). We show that a variant of this approach yields a filtration that is asymptotically only marginally larger than the tower a...

An analysis of the mechanics of extracting blocks from a tower of stacked blocks in the game of Jenga is presented. Translational and rotational moves are analyzed for the likelihood of disturbing other blocks in the tower, with an aim to determine moves which are safe from disturbing other blocks and are robust against change in outcome with different block configurations. Optimal moves are fo...

The explicit construction of function fields tower with many rational points relative to the genus in the tower play a key role for the construction of asymptotically good algebraic-geometric codes. In 1997 Garcia, Stichtenoth and Thomas [6] exhibited two recursive asymptotically good Kummer towers over any non-prime field. Wulftange determined the limit of one tower in his PhD thesis [13]. In ...

This paper presented an overview on the dynamic analysis and control of the transmission tower-line system in the past forty years. The challenges and future developing trends in the dynamic analysis and mitigation of the transmission tower-line system under dynamic excitations are also put forward. It also reviews the analytical models and approaches of the transmission tower, transmission lin...

Understanding the impulse response of tower grounding systems is a key factor in the determination of the lightning performance of transmission lines and the safety voltages near high voltage towers. This paper reports the results of an experimental study on the impulse characteristics of full-scale transmission line tower footings. The ground potential distribution both at the ground surface a...

27 28 The simulation of center-pivot performance has been the subject of research 29 efforts since the 1960s. Center-pivot models frequently use empirical equations 30 relating pressure and sprinkler radial application pattern. Individual, stationary 31 water application patterns are overlapped and the resulting water application is 32 mapped in the field. Such models use constant tower angular...

This paper is an attempt to Numerical Modeling and Experimental Study of Air Flow in the Yazdi Wind-Towers. Wind Towers has been known as one of the most effective climatic elements in Iranian traditional architecture. This paper is an attempt to evaluating Yazdi wind-tower to discussion the two main questions: 1. What is the role of Orientation of wind-towers span, regarding to climate and he...
