Solution: In the given Fender-Wheel assembly, at section C, D, E has lower clearance than clearance required. But in section D, E has negative clearance (means wheel is outer side to fender). Due to such reasons the given Fender- Wheel assembly was failed as per Europian Standards. links for 1.wheel-arc report https://drive.google.com/drive/folders/1sHDHfIpgEBfaklY-EA2f-25NQW3xMXyi?usp=sharing…

Undercoating  is a thick resilient coating applied to the underbody or chassis of an automobile to protect against impact damage from small stones, which would rapidly chip ordinary paint, allowing rusting to begin.  It is also used to protect the parts like internal body panels,…

SEDAN is the right choice to commute to office in highly crowded city(Bangalore) and also to visit native(Madurai) once in a month. Best car among sedan between 8 to 10 lakhs: In petrol engine:Maruti suzuki CIAZ In diesel engine: 1) HONDA AMAZE(Including Child)                  …

    Symmetry Boundary Condition: Generally we will encounter an analysis where you need more computer memory and/or CPU speed that you can obtain. Therefore you should get familiar with methods for using efficient modeling techniques. One method of efficiently using finite volume method(FVM) modeling is to exploit…

Axisymmetric Flow & Wedge boundary condition: Axisymmetric Flow: The flow which possesses an axis of symmetry along a central line such that all physical variables of the flow have the same value and distribution at a given radius for all angles with respect to this axis are called as axisymmetric flow. The cylindrical…

FINITE DIFFERENCE METHOD: Finite difference methods is the numerical schemes used to solve partial differential equations. It consists in approximating the differential operator by replacing the derivatives in the equation using differential quotients. The domain is partitioned in space and in time and approximations of…

Backward Facing Flow: when flow enters the domain from inlet,after some time the flow reaches the step, because of expansion of flow channel, pressure gradient exists, it detaches and a recirculation zone is formed. A turbulent boundary layer encounters a sudden back step, causing flow separation. Later the flow eventually…

QUASI 1D SUBSONIC-SUPERSONIC NOZZLE: A quasi-one-dimensional flow is one in which all variables vary primarily along one direction,say x. A flow in a duct with slowly-varying area A(x) is the case of interest here. In practice this means that the slope of the duct walls is small. Also, the x-velocity component u dominates…

Given condition: 2D HEAT CONDUCTION EQUATION `(delT)/(delt)=alpha((del^2T)/(del^2x)+(del^2T)/(del^2y))` Boundary condition: Top Boundary(T_top) = 600 K Bottom Boundary(T_bottom) = 900 K Left Boundary(T_left) = 400 K Right Boundary(T_right) = 800 K Absolute error criteria (error_tol)= 1e-4 OBJECTIVE:Solve Steady state and…

FORWARD DIFFERENCE: Consider a linear interpolation between the current data value `(t_0,x_0)`and the future data value `(t_1,x_1)`. The slope of the secant line between these two points approximates the derivative by the forward (two-point) difference:                …
