This paper describes the current efforts to develop and manufacture a first prototype for a boundary layer pump as a mean to assess future and more complex designs. Following an approach of “learning by doing”, a previous design was re-assessed from a mechanical/workshop point of view. Budget constraints and in-house manufacturing capabilities were taken into consideration to deliver a new design, suitable for quick production. Challenges such as disc holding, gap spacing, pump intake, discharge nozzles, and tolerances were addressed. Structural analysis has been conducted; where every single component has been modelled and sized accordingly to standard practices. As a support of structural analysis, FEM analysis was also performed with the aim of identifying, discussing, and fixing any potentially critical issues, particularly regarding the bolts holding together the discs into the power shaft. Finally, modal analysis was performed in order to test the dynamic response of the rotor: its critical frequencies would be far from the working range of the machine. This paper gives an overview of the critical issues to be taken into account during the mechanical design of boundary layer pump prototypes for different working fluids in the field of power generation and thermal management.

“…The uniqueness of this pump is that the mechanical energy is transferred to the fluid by rotation of flat disks without blades to ensure good hemocompatibility of the pump. The construction principles of the Tesla pump have been known for many years [22,23]. However, construction of the bladeless heart pump presented in this paper is significantly different.…”

“…While the Penn State University continuous flow left ventricular assist device has the same basic principle of several flat rotating disks, the flow throughout the pump is different because of the particular geometry of the inlet and outlet placement [22]. In this paper, the previously published concept of a bladeless continuous flow heart pump (Figure 1) is further developed and improved using numerical analysis and computational The construction principles of the Tesla pump have been known for many years [22,23].

Bladeless Heart Pump Design: Modeling and Numerical Analysis

In this paper, the design of a new type of heart pump is presented. The uniqueness of this pump concept is that the mechanical energy is transferred to the fluid by the rotation of flat disks without blades. Both theoretical and numerical analysis are used to determine the pump design parameters. The pump design parameters are calculated using the Navier-Stokes equations. The application of computational fluid dynamics is used to define the geometric design. The pump head and flow have to be within strictly defined limits to ensure normal blood circulation. The negative impact of the pump on the blood must be minimal (no stagnation and recirculation zones, shear stress in the acceptable range). It is also important to achieve the smallest possible pump volume. For the pump operating point of ∆p = 65 mmHg, Q = 5.43 L/min, and ω = 6000 rpm, the design parameters are inner radius R1 = 12 mm, outer radius R2 = 15 mm, the distance between disk of h = 1 mm, and the number of disks is n = 6. The shear stress in the rotor is in range 46–108 Pa and the pump residence time is 0.0194 s.

“…Boundary layer pumps have become an increasingly researched area of alternative turbomachinery due to their simplistic design of concentrically stacked, smooth discs, offering a more cost-effective solution to conventional, bladed turbomachinery [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. A boundary layer pump's working principle is based on the Coanda effect [18] and kinetic energy is transmitted from the rotor to the fluid only by frictional forces which makes boundary layer pumps more suitable for some specific applications such as non-Newtonian fluids at which bladed turbomachinery cannot operate efficiently.…”

A flow field analysis of a realistic, integrated, multi-disc boundary layer pump as is necessary for investigating the reasons for typically quoted low efficiencies in such pumps is described. The study focuses on the 3D RANS solutions of a water boundary layer pump model created to replicate a design which consists of 170 discs and a volute channel. A baseline study is performed to investigate the rotor-only and volute-only flow fields and identify the losses in each as separate systems. Thereafter, an integrated model is characterized for different operating conditions. The flow fields of all three models are discussed and the results of the integrated model are compared to the experimental data. The results from the rotor-only model confirm the typically made claim that the rotor efficiency is relatively high, which in this case is 87% at the design point. The volute on its own indicated a hydraulic efficiency of ~97%. However, the integrated model yielded a rotor efficiency of ~74% and an overall pump efficiency of 51% at the design point, clearly outlining the fact that the effect of the volute integrated with the rotor is the reason for both the rotor and pump efficiency degradation. The reason for this drop in efficiency is discussed by highlighting the change in the flow topologies. The insights into the flow field and the identification of the reason for inefficiencies using a separated component analysis approach provides directions for avenues in which design improvements need to be attempted.
