Journal bearing is an important component of any machine such as in crankshaft of automobile engine. It helps to reduce friction and allow motion in required direction and restrict them in other direction. There is different type of bearings such as ball bearing, roller bearing, journal bearing etc. In this course we are going to solve numerically journal bearing with given conditions and geometric parameters. At the end of course you will validate CFD results shown in this course with data from Shigley's Mechanical Engineering Design Book.First, we will start with discussion on bearings and types. Then we will discuss about the journal bearings, different terms such as eccentricity, eccentricity ratio, clearance. We will also discuss the design parameters for journal bearing solved in this course as well. After that we will discuss about the material properties, whether flow is laminar or turbulent, Sommerfeld number and corresponding optimum parameters from Shigley's book. We will also go through modelling approaches such a full Sommerfeld, half Sommerfeld or cavitation modelling through multiphase modelling in CFD. Then we will create geometry in Spaceclaim, hexa mesh in ICEMCFD and subsequently problem setup and simulation in Fluent.After solving problem in Fluent, we will obtain results by post processing in Fluent and CFD post. Specially plotting the static pressure around circumference of journal and displaying it as pressure vs angular coordinates from 0 to 360 degrees. We will also find out the value of loading on bearing in reverse fashion by finding out the value of maximum pressure and maximum pressure ratio of film thickness. We will also show the angular position of maximum pressure and zero pressure. We will compare them with data we get from Shigley's Mechanical Engineering Design Book. I have found that resultss are matching very well and thus validation is done perfectly.

This comprehensive course is designed for students, engineers, researchers... to be able to use COMSOL Multiphysics from scratch to conduct physical simulations in a simple and practical way. Never mind if you have no experience in Finite Elements or COMSOL, you will be equally capable of understanding everything and you will finish the course with mastery of the subject.After several years working as an Industrial Engineer, I have realized that mastering the Finite Elements to solve physical problems today is something very necessary in engineering and is really sought. And in addition, the demand is increasing. Knowing how to carry out this type of simulation can give you many job opportunities and many economic benefits.And as if that were not enough, solving these simulations in COMSOL will offer you even more advantages, since it is a very complete software that offers you a multitude of physical modules for simulation, such as structural, mechanical, frequency or CFD (Computational Fluid Dynamics)... For this reason, in just a few years it has become one of the leaders in the sector and one of the programs most sought by companies in the figure of the engineer.The big problem has always been the complexity to learn that it requires, since its understanding is not easy. In this course I try to facilitate this entire learning and improvement process, and you will be able to carry out and understand your own problems in a short time, as well as their physical sense and the logic of the procedure, thanks to the step-by-step and detailed resolution of 5 complete on-demand problems in which you will master the main and different physical applications of COMSOL Multiphysics:STRUCTURAL PROBLEMS: With this problems you will learn to carry out structural simulations and and will understand solid mechanics physics thanks to two problems; a static analysis of a wrench (stationari study) and a dynamic analysis (time dependent study

One of the greatest transformations that we will see in the next couple of decades is going to be the advent of autonomous drones. While being used extensively already, the applications of quadcopters will only grow in time. Drones will be used in delivery services, entertainment, medicine, military, rescue, structural quality inspection - places that people cannot reach easily, and in many other fields. In many cases, there will be a predefined trajectory in a 3D space that the UAV needs to follow without human help. In fact, humans might simply give a simple command for the drone to go somewhere, and then, a specific trajectory will be generated by a computer in that direction and the UAV's control algorithms will need to determine EXACTLY how fast each rotor should turn in order to make the drone follow that trajectory with high-degree precision. And that's what this course is all about - its about DESIGNING, MASTERING, and APPLYING these control algorithms together with deriving the dynamics equations for the quadcopter.In this course, you will receive a full package when it comes to learning about how to model and control a UAV drone and make it follow a trajectory in a 3D environment. Not only you will learn how to model a UAV system mathematically by deriving the equations of motion using the principles of 3D Dynamics, but you will also be exposed to some of the most powerful control techniques out there such as Model Predictive Control and feedback linearization.In 3D dynamics, you will learn the fundamental math and physics behind the UAV quadcopter drone modelling. You will learn how to describe the position and orientation of a UAV quadcopter drone in a 3D space using rotation and transfer matrices, Newton - Euler 6 Degree of Freedom equations of motion, widely used Runge - Kutta integrator in engineering and propeller dynamics.In the end of the course, I will also explain to you the code in the Python simulator.Understanding the m

In this course, we'll learn about the Fundamentals of Electrical, Electronics engineering, and Coding.Here we are using Tinkercad Platform the open-source electronics simulation and programming platform.By attending this course you will not have fear of coding Arduino. We will learn about coding the Arduino most simply. We will learn about how to interface the different sensors with the Arduino. How do the sensors work what is the operating principle? We will interface electric motors with Arduino and try to create real-life projects using the same. But what’s different in this course is that I have tried to explain every minute detail, so that you will never have a doubt, from understanding how the sensor works to interfacing the sensor with Arduino. We will clear all complex concept most simply and you will never feel electronics Coding is difficult.Even If you do not have any experience with programming or electronics, that’s OK! Because this course is designed for the absolute beginners. We are going to start understanding Arduino and learn the basics of electrical electronics engineering.We will learn about how to make the traffic lights project and how they are programmed to control the flow of traffic.Then, we are going to learn what is a buzzer and how we can able to control the buzzer using the push buttonAnd after that, we will understand what is a sensor, learn about two types of sensors is a digital sensor and an Analog sensor and we will make a motion detector project. Following that, we are going to see how to interface analog sensors with an Arduino and we will create different projects like smart LED using LDR sensor, obstacle detector using ultrasonic sensor,Controlling buzzer and led using flex sensor, detecting the force applied on objects using f
