En este contexto, el presente estudio experimental muestra los resultados obtenidos al medir el movimiento de grandes esferas de di\u00e1metro que caen vertical y gravitacionalmente en un recipiente cil\u00edndrico de di\u00e1metro interno , que contiene una soluci\u00f3n acuosa de carboximetilcelulosa (CMC) bajo concentraciones masa\/volumen () en el rango 10 a 15 g\/L. Las soluciones se comportan reol\u00f3gicamente como fluidos adelgazantes sin tensi\u00f3n de fluencia (y =0), de modo que su ley constitutiva se describe por la relaci\u00f3n () = ^, donde y son coeficientes reol\u00f3gicos. Se realizaron varias campa\u00f1as experimentales variando el tama\u00f1o de las esferas, monitoreando su trayectoria con t\u00e9cnicas<br \/>\nde fotogrametr\u00eda. Se determin\u00f3 que la velocidad de sedimentaci\u00f3n de estos objetos est\u00e1 influenciada por efectos viscoel\u00e1sticos del fluido durante la penetraci\u00f3n inicial, seguido por un r\u00e9gimen de equilibrio donde la velocidad es constante, que puede expresarse en t\u00e9rminos de la velocidad de Stokes introduciendo un factor correctivo dependiente de la concentraci\u00f3n y de la relaci\u00f3n \/.<\/p>\n<p>1 Profesor Auxiliar, Escuela de Ingenier\u00eda Civil, PUCV &#8211; email: francisco.martinez@pucv.cl<br \/>\n2 Profesor, Departamento de Ingenier\u00eda Civil, UNAL (Colombia) \u2013 email: pchang@unal.edu.co<br \/>\n3 Ingeniera Civil, Escuela de Ingenier\u00eda Civil, PUCV \u2013 email: camila.marambio.s@mail.pucv.cl<br \/>\n4 Ingeniero Civil, Escuela de Ingenier\u00eda Civil, PUCV \u2013 email: camilo.moris.r@mail.pucv.cl<\/p>\n<div class=\"wpfilebase-file-default\" onclick=\"if('undefined' == typeof event.target.href) document.getElementById('wpfb-file-link-1').click();\">\r\n  <div class=\"icon\"><a href=\"https:\/\/www.sochid.cl\/?wpfb_dl=1608\" target=\"_blank\" title=\"Download CAIDA VERTICAL DE ESFERAS EN SUSPENSIONES POLIMERICAS PSEUDOPLASTICAS PURAS\"><img decoding=\"async\" align=\"middle\" src=\"https:\/\/www.sochid.cl\/wp-includes\/images\/crystal\/document.png\" alt=\"CAIDA VERTICAL DE ESFERAS EN SUSPENSIONES POLIMERICAS PSEUDOPLASTICAS PURAS\" \/><\/a><\/div>\r\n  <div class=\"filetitle\">\r\n    <a href=\"https:\/\/www.sochid.cl\/?wpfb_dl=1608\" title=\"Download CAIDA VERTICAL DE ESFERAS EN SUSPENSIONES POLIMERICAS PSEUDOPLASTICAS PURAS\" target=\"_blank\" id=\"wpfb-file-link-1\">CAIDA VERTICAL DE ESFERAS EN SUSPENSIONES POLIMERICAS PSEUDOPLASTICAS PURAS<\/a>\r\n    \r\n    <br \/>\r\n    MartinezFrancisco_TrabajoSOCHID_revfinal.pdf<br \/>\r\n    \r\n  <\/div>\r\n  <div class=\"info\">\r\n    0 B<br \/>\r\n    96 Downloads<br \/>\r\n    <a href=\"#\" onclick=\"return wpfilebase_filedetails(1);\">Detalles<\/a>\r\n  <\/div>\r\n  <div class=\"details\" id=\"wpfilebase-filedetails1\" style=\"display: none;\">\r\n  \r\n  <table border=\"0\">\r\n   \r\n   <tr><td><strong>Autor:<\/strong><\/td><td>FRANCISCO MART\u00cdNEZ<\/td><\/tr>\r\n   <tr><td><strong>Platforms:<\/strong><\/td><td>Windows 8<\/td><\/tr>\r\n   \r\n   <tr><td><strong>Category:<\/strong><\/td><td>HF12<\/td><\/tr>\r\n   <tr><td><strong>License:<\/strong><\/td><td>Freeware<\/td><\/tr>\r\n   <tr><td><strong>Fecha:<\/strong><\/td><td>9 mayo, 2026<\/td><\/tr>\r\n  <\/table>\r\n  <\/div>\r\n <div style=\"clear: both;\"><\/div>\r\n<\/div>\n","protected":false},"excerpt":{"rendered":"<div class=\"mh-excerpt\"><p>CAIDA VERTICAL DE ESFERAS EN SUSPENSIONES POLIMERICAS PSEUDOPLASTICAS PURAS FRANCISCO MART\u00cdNEZ (1) PHILIPPE CHANG (2) CAMILA MARAMBIO (3) CAMILO MORIS (4) Las suspensiones polim\u00e9ricas participan <a class=\"mh-excerpt-more\" href=\"https:\/\/www.sochid.cl\/?p=11895\" title=\"Congreso XXVII &#8211; HF1-2\">[&#8230;]<\/a><\/p>\n<\/div>","protected":false},"author":3149,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[78],"tags":[],"class_list":["post-11895","post","type-post","status-publish","format-standard","hentry","category-congreso-xxvii"],"_links":{"self":[{"href":"https:\/\/www.sochid.cl\/index.php?rest_route=\/wp\/v2\/posts\/11895","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sochid.cl\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sochid.cl\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sochid.cl\/index.php?rest_route=\/wp\/v2\/users\/3149"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sochid.cl\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=11895"}],"version-history":[{"count":3,"href":"https:\/\/www.sochid.cl\/index.php?rest_route=\/wp\/v2\/posts\/11895\/revisions"}],"predecessor-version":[{"id":11898,"href":"https:\/\/www.sochid.cl\/index.php?rest_route=\/wp\/v2\/posts\/11895\/revisions\/11898"}],"wp:attachment":[{"href":"https:\/\/www.sochid.cl\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=11895"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sochid.cl\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=11895"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sochid.cl\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=11895"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
