Abstract\u200b: <\/p>\n Simulation of such machines still requires highly skilled engineers, use of advanced simulation tools and advanced simulation approach \u2026 despite the availability of modern simulation tools with well suited graphical user interface (GUI) and numerical techniques.<\/p>\n <\/p>\n The paper presents recent activities and progress on simulation of hydrostatic machines \u2013 in particular, the axial piston pump and the radial hydraulic motor. Despite that these machines have been designed and produced by Poclain for decades, there are still (design) features and phenomena not being investigated in detail or never being simulated.<\/p>\n <\/p>\n The simulation advancements mainly refer to the application of complicated kinematic motion, fluid properties, physics to consider as well as mesh and numerical algorithm techniques. In this paper, the focus is given on modelling of advanced fluid properties (e.g. compressibility, cavitation etc.). Fluid with such advanced properties is used in fluid flow simulation.<\/p>\n <\/p>\n Numerical approach has been performed by means of computational fluid dynamic (CFD) within the environment of Siemens Simcenter Star-CCM+. The anticipation of cavitation has been possible by implementation of existing \u00bbfull cavitation model\u00ab. <\/p>\n <\/p>\n Keywords: <\/p>\n Copyright (c) 2026 An\u017ee \u010celik <\/p>\n This work is licensed under a <\/p>\n Except where otherwise noted, articles in [\/et_pb_text][et_pb_button button_url=”https:\/\/revija-ventil.si\/wp-content\/uploads\/celik-04-2026.pdf” url_new_window=”on” button_text=”Download PDF” admin_label=”Gumb Prenesi PDF” _builder_version=”4.27.6″ custom_button=”on” button_text_size=”15px” button_text_color=”#00868a” button_bg_color=”rgba(0,0,0,0)” button_border_color=”#00868a” button_icon=”||divi||400″ custom_margin=”||0px||false|false” custom_margin_tablet=”||20px||false|false” custom_margin_phone=”” custom_margin_last_edited=”on|desktop” custom_padding=”||||false|false” hover_enabled=”0″ locked=”off” global_colors_info=”{}” button_border_color__hover_enabled=”on|hover” button_border_color__hover=”#00868a” theme_builder_area=”post_content” sticky_enabled=”0″][\/et_pb_button][et_pb_post_nav in_same_term=”on” prev_text=”Older entries” next_text=”Newer entries” admin_label=”Navigacija po objavah” _builder_version=”4.3.3″ custom_margin=”||||false|false” custom_margin_phone=”||||false|false” custom_margin_last_edited=”off|desktop” custom_padding=”20px||||false|false” custom_padding_tablet=”0px||0px||false|false” custom_padding_phone=”0px||0px||false|false” custom_padding_last_edited=”on|tablet” title_text_color_last_edited=”off|desktop” global_module=”11763″ locked=”off” global_colors_info=”{}” title_text_color__hover_enabled=”on|desktop” title_text_color__hover=”#212b31″ theme_builder_area=”post_content”][\/et_pb_post_nav][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||” theme_builder_area=”post_content”][et_pb_sidebar orientation=”right” area=”et_pb_widget_area_4″ disabled_on=”on|on|off” _builder_version=”4.27.4″ global_module=”11764″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_sidebar][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" Hydrostatic machines are devices that transfer power using pressurized hydraulic fluid within a closed circuit, relying on positive displacement pumps and motors.
