dc.description.abstractLas bombas centrífugas son de gran utilidad industrial y dentro de sus aplicaciones se puede encontrar el bombeo de fluidos que contienen microorganismos vivos en suspensión. Sin embargo, este tipo de bombeo puede afectar el desarrollo de los microorganismos, ya que genera altos esfuerzos cortantes, que no son soportables por sus paredes celulares, lo cual se traduce en una elevada mortalidad celular. En este artículo se analizó computacionalmente una bomba centrífuga utilizada para el bombeo de cultivos microalgales en fotobiorreactores tubulares. Para ello, se modeló la geometría tanto de la voluta como del impeler en CAD, para posteriormente efectuar una simulación en CFX según las condiciones de operación de un fotobiorreactor. La evaluación de la distribución de velocidad y de los esfuerzos cortantes dentro de la bomba llevó a concluir que es inviable la utilización de estos mecanismos de bombeo, dada la alta mortalidad que se puede presentar para ciertas especies microalgales, como es el caso de la Chaetoceros muel-leri, en la cual su viabilidad se puede reducir hasta niveles del 52%spa
dc.description.abstractIndustrially, the centrifugal pumps are very useful and within their applications, it can be found pumping fluids containing living microorganisms in suspension. However, this type of pumping can affect the growth of microorganisms because it generates high shear stresses, which are not supported by their cell walls, resulting in high cell mortality. In this article, we analyzed computationally a centrifugal pump used for pumping microalgal cultures in tubular photo-bioreactors. To do this, we modeled in CAD both the impeller and the volute; and then we conducted a simulation in CFX under the operation conditions of a photobioreactor. The evaluation of the velocity distribution and shear stresses inside the pump, led to conclude that it is impractical to use these pumping mechanisms, due to the high mortality rate that is expected for some microalgae species, such as the Chaetoceros muelleri; for which its viability can be reduced to levels of 52%"eng
