Se realizó una simulación numérica de la geometría bidimensional de un reactor de gasificación por plasma con el fin de conseguir un rendimiento optimizado con el uso del software COMSOL Multiphysics. Se definieron condiciones iniciales del reactor y se crearon 16 distintas combinaciones geométricas que varían cuatro aspectos geométricos del reactor: los radios inferior y superior de la cámara de gases, la longitud central de la cámara y el volumen de la cámara de fundición. De estas, fueron halladas dos combinaciones que optimizan los aspectos de mezclado de gases y transferencia de calor hacia el ambiente. Se confirmó que los diseños planteados alcanzan las temperaturas necesarias para la fundición y gasificación de los desechos. Además, el material fundido teórico alcanza la viscosidad necesaria menor a 10 Pa s para poder fluir fuera del reactor.]]></p></abstract>

Here, numerical simulation utilizing the COMSOL Multiphysics software was used to achieve an optimized bidimensional geometry. Initial conditions for the reactor were defined using the researchers&#8217; experience. Then, 16 different combinations of four geometric parameters were set, where the gas chamber&#8217;s superior, and inferior radius, it&#8217;s length and lastly the fusing chamber volume were varied. Of these, two combinations that optimized the mixing of gases and heat exchange with the exterior were found. It was confirmed that these designs allowed for the proper melting and gasification of the theoretical waste. Further, the smelted material also possessed a viscosity lower than 10 Pa s needed to flow out of the reactor.]]></p></abstract>
