A Practical RANS-Based Design on a Tandem Propeller for Energy Saving

The team have developed an innovative dual-blade propeller design that boosts marine transportation efficiency by 3%. By carefully positioning two propeller blades, the new design increases propulsion efficiency from 74.8% to 77.8%, promising significant fuel savings and reduced environmental impact for the shipping industry.

U.S. Patent 11,333,172: Air moving device with stator blade structure

The air moving device includes a rotor and a stator. The quantity of the rotor blades is not less than 5 and not greater than 12. The average blade angle of rotor blades is not less than 45 degrees and is not greater than 64 degrees. The ratio of the hub diameter to the rotor diameter is not less than 0.4 and not greater than 0.79. The quantity of the stator blades is not less than 6 and not greater than 23. The average blade angle of stator blades is not less than 45 degrees and not greater than 70 degrees. The ratio of the total thickness of the air moving device to the rotor diameter is not less than 0.76 and not greater than 1.7. The ratio of the stator axial thickness to the rotor axial thickness is not less than 0.28 and not greater than 0.65.

Efficiency Analysis of Flapping Foil Propulsion

This study numerically simulated flapping foil propulsion efficiency using SC/Tetra software. It analyzed the impact of rotation axis location, flapping frequency, and angle to find the optimal combination for maximum efficiency. The results showed a peak efficiency of 74.3% when the rotation axis was 0.3 chord lengths from the leading edge, the flapping angle was 30 degrees, and the Strouhal number was 0.2. The study also highlighted that this specific rotation axis position leads to higher efficiency with reduced power.

U.S. Patent 11,359,641: Air moving device with blade tip of variable curvature

This disclosure provides an air moving device with blade tip of variable curvature. The axial air moving device includes a hub and a plurality of blades. The blades are connected with the hub, and each blade is configured by stacking multiple wing sections continuously. Each blade includes a blade root and a blade tip. The span position of the blade at the blade root is defined as 0, and at the blade tip is defined as 1. The blade angle is defined by the nose-tail line of the wing section and the rotation direction of the axial air moving device. The blade angle of the wing section at the blade tip of the blade is at least 10 degrees less than the blade angle of the wing section at the span position of 0.8 of the blade.

An Investigation on the Tandem Propeller with High Aspect Ratio Blade for Energy Saving

This paper explores a high aspect ratio tandem propeller for saving energy in marine transport. A conventional propeller is modified using Computational Fluid Dynamics (CFD) to analyze its performance with different phase angles. The key finding is a consistent propulsion efficiency increase of about 2.1%. Placing rear blades within front blade wakes is important for optimal results. This simple tandem propeller is a promising way to improve marine propulsion efficiency.

U.S. Patent 11,486,402: Counter-rotating axial air moving device structure

A counter rotating axial air moving device structure is disclosed. The rear rotor includes a rear hub and rear blades, and a pitch angle of each of the rear blades increases gradually in a direction away from the rear hub. The front rotor, the rear rotor and the stator component are stacked with each other. The ratio of the thickness to the diameter is equal to or greater than about 0.25 and equal to or less than about 0.8. Therefore, a better performance curve is obtained, and the vibration and noise are avoided.

U.S. Patent 11,512,704: Counter-rotating axial air moving device

A counter-rotating axial air moving device includes a front rotor and a rear rotor. The front rotor includes a front hub and a plurality of front blades, and the number of the front blades is equal to or greater than 7 and equal to or less than 11. The rear rotor is disposed on the downstream side of the front rotor. The rear rotor includes a rear hub and a plurality of rear blades, and the number of the rear blades is equal to or greater than 6 and equal to or less than 10. The front rotor and the rear rotor are stacked with each other with a total thickness and a diameter. The ratio of the total thickness to the diameter is equal to or more than 0.91 and equal to or less than 1.5.

U.S. Patent 11,536,279: Thin type counter-rotating axial air moving device

This disclosure is related to a thin type counter-rotating axial air moving device. The ratio of the front hub diameter to the front blade diameter is about 0.3 to about 0.85. The front average pitch angle of the front blades is greater than about 46 degrees. The ratio of the rear hub diameter to the rear blade diameter is about 0.3 to about 0.85. The rear average pitch angle of the rear blades is less than about 38 degrees. The ratio of the total thickness to the greater one between the front blade diameter and the rear blade diameter is less than or equal to about 0.75.

U.S. Patent 11,873,835: Manufacturing method of axial air moving device with blades overlapped in axial projection

A manufacturing method of an axial air moving device. A model of the axial air moving device includes a hub and blades. The axial projection of blades is partially overlapped in the axial direction of the hub. The model of the axial air moving device is parted in the axis direction of the hub. The blades are divided into multiple parting models non-overlapped in the axial projection. A mold manufacture using axial demolding and an injection molding are performed and the parting models are connected. Therefore, the axial air moving device with overlapped blades and better fluid performance is achieved through the axial demolding method.

應用人工智慧於風扇自動 CFD 設計

本文結合人工智慧與利用 CRADLE CFD 建置之全自動 CFD 分析設計系統,進行了四種不同構造、不同變數數目與不同樣本數的機器學習最佳化探討。初步歸結,此模式對交互作用複雜的情況,具有比傳統最佳化方式更快更好的設計效能。本法應用於 1U 伺服器風扇設計,開發出目前唯一能以動靜葉構造達成傳統對轉風扇效能的獨特設計,可因減少一個馬達而大幅降低成本。

應用 CRADLE CFD 考慮系統真實幾何之熱管理行為暨噪音分析

由傳統簡化法與考量真實幾何法對一 電子系統的分析比較可知,傳統簡化法對稠密系統之分析預測較為粗略,考量真實幾何之結果較為精細;傳統簡化方式會低估溫度預測,使得設計過於樂觀。在越來越稠密和熱密度越來越高的新電子產品趨勢下,這樣的缺失將越來越被凸顯。CRADLE scFLOW 的軟體能力已可以合理的時間進行真實幾何系統的直接分析,得到較為精確的結果並可進一步同時包括系統與真實風扇旋轉進行氣動噪音分析,使散熱與噪音都能進行同步協 同分析,整合設計 。
