Experimental and Computational Studies of the No-Load Churning Loss of a Truck Axle

SAE Technical Paper Series, 2020
<div class="section abstract"><div class="htmlview paragraph">This paper describes the work performed in predicting and measuring the contribution of oil churning to the no-load losses of a commercial truck axle at typical running speeds. A computational fluid dynamics (CFD) analysis of the churning losses was conducted.

Churning losses of spiral bevel gears at high rotational speed

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2019
In the present study, no-load losses of different splash lubricated spiral bevel gears were measured. The authors used a specific test rig, and a set of gears, to investigate churning losses at higher tangential speeds: up to 60 m/s. An uncommon behavior of the drag torque was highlighted: the torque increased with the rotational speed until a local ...

Optimization of Oil Quantity in Manual Transmission and Reducing Churning Loss

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">The gearbox is a crucial aggregate in a diesel truck. Gearboxes must work efficiently to get the job done properly and lubrication is vital to this efficiency. Lubricating oil is like the circulation system of a gearbox.

Churning Loss Estimation for Manual Transmission Gear Box Using CFD

SAE International Journal of Passenger Cars - Mechanical Systems, 2015
<div class="section abstract"><div class="htmlview paragraph">Fuel economy is one of the factors that drives the automobile sector today, and the demand for fuel efficient vehicles continues to increase by the day. Power loss in the vehicle driveline directly affects the fuel economy and must be reduced to achieve maximum fuel economy ...

Customer churn rate / attrition rate: prediction of customer loss

2019
Χαμένη πελατεία ορίζεται συνήθως η πιθανότητα ένας πελάτης να διακόψει εθελοντικά ένα υπάρχον/ουσα συμβόλαιο-σύμβαση μέσα στους επόμενους Χ μήνες, όπου ο αριθμός Χ καθορίζεται σύμφωνα με τον τύπο της επιχείρησης και το είδος του προβλήματος πιο συγκεκριμένα. Αναφέρεται επίσης και ως απώλεια πελατών. (Forecast Analytics,2015).
