Abstract
The duct of a robot vacuum cleaner is the length of the flow channel between the inlet of the rolling brush blower and the outlet of the vacuum blower. To cope with the pressure drop problem of the duct flow field in a robot vacuum cleaner, a method based on Pressure Implicit with Splitting of Operators (PRISO) algorithm is introduced and the optimisation design of the duct flow field is implemented. Firstly, the duct structure in a robot vacuum cleaner is taken as a research object, with the computational fluid dynamics (CFD) theories adopted; a three-dimensional fluid model of the duct is established by means of the FLUENT solver of the CFD software. Secondly, with the k-∊ turbulence model of three-dimensional incompressible fluid considered and the PRISO pressure modification algorithm employed, the flow field numerical simulations inside the duct of the robot vacuum cleaner are carried out. Then, the velocity vector plots on the arbitrary plane of the duct flow field are obtained. Finally, an investigation of the dynamic characteristics of the duct flow field is done and defects of the original duct flow field are analysed, the optimisation of the original flow field has then been conducted. Experimental results show that the duct flow field after optimisation can effectively reduce pressure drop, the feasibility as well as the correctness of the theoretical modelling and optimisation approaches are validated.

Summary
It is known that household cleaning is a series of repeated and tedious manual tasks, carried out by thousands of people every day. How to optimise the duct flow field inside the robot vacuum cleaner has become important. A8n, dNoH.u5a,-s1h0a4n-1L1iu2: 104 Research on Duct Flow Field Optimisation of a Robot Vacuum Cleaner significant impact on the fluid dynamics performance of the entire duct system. Ishtiaque et al.[5] modified the design of the transport duct and analysed the air‐flow inside the transport duct with the computational fluid dynamics (CFD) software FLUENT after creating the transport duct geometry in the geometrical model software GAMBIT. The present paper focuses on the duct flow field optimisation of the robot vacuum cleaner. The flow field analysis of original duct structure inside the robot vacuum cleaner is carried out using the computational fluid dynamics software FLUENT after creating the duct geometry in the geometrical model software Pro/Engineer. All the results validate the effectiveness and correctness of the modelling in the paper
