In this paper, we are present the performance of engine coolant hoses (radiator hoses) used in passenger cars by checking various physical behaviours such as hose leakage, hose burst, hose collapse or any mechanical damage as studied-thru design guidelines, CFD analysis and product validation testing and also check pressure drop of the hoses when engine will be running. The design term is more likely used for technical part modelling using CAD tool. Later on, we will focus on the transformation of the part design to process design. The process design term is more likely used for "tooling design" for manufacturing of the product using CAD Tool. Then inlet hose carries coolant from engine to radiator inlet tank, then coolant circulated in radiator and passed through radiator outlet tank to water pump of engine with the help of outlet hose. After that …nding any leakage, Burst, damage or collapse of hose and pressure drop of the hose with the help of design checklist, CFD Analysis and product validation testing.

In this paper, we study existence and uniqueness of solutions for a coupled system of multi-point boundary value problems for fractional di¤erential equations. Applying principle contraction and Shaefer's fixed point theorem new existence results are obtained.

In order to design multi-phases permanent-magnet (PM) synchronous machines (PMSMs), a simplified analytical method is used to calculate the various geometrical parameters. The winding of the machines is concentric with two layers and the PMs are mounted on the rotor surface. The sizing model is coupled to an optimization process based on genetic algorithm (AG). The Pareto front obtained from the optimization, made it possible to choose the optimal solution. The optimal variables are injected into the model to calculate the di¤erent parameters. The optimization results are then used for two-dimensional (2-D) finite-element simulation, where a power balance is established for each multi-phases PMSMs.
